Social software and the problem of trust

Friday, November 30th, 2007

Although you don’t hear about it much, trust is an extremely important issue in the software world.  A common example is eBay – how could eBay stay in business if millions of anonymous buyers and sellers didn’t have a certain level of trust?

Andy Brice, a software developer, gives a really interesting example of the problem of trust in his blog.  He became concerned that his software products were getting a ridiculous number of awards and 5-star ratings from shareware download sites.  He devised an experiment: if you create a text file, change the file extension to .exe, and submit it to 700 download sites, how many award would you get?

It turns out you would get tons of awards.  A large percentage of these sites, which ostensibly provide users the service of evaluating shareware and freeware, are in reality just trying to skim adwords revenue.

Social software, if applied correctly with enough participation, can help to solve this problem.  It is much harder to fake 1000 del.icio.us bookmarks than it is to make an authoritative-looking award banner.

Many of us work on projects internal to companies where we don’t confront these issues directly on a day-to-day basis.  Large companies can generate billions of pages of documents and code each year.  Add to that the billions of external web pages we use as reference material.  Tools such as social bookmarking can help build up this network of trust and sift through the less useful resources even on intranets.

So now that we have the tools available, all we need is participation.  You’re reading this, so I’m probably already preaching to the choir.  Trust is a really interesting issue, though, so I’ll be writing about it here and there in the future.

The iPhone, Google Maps for Mobile, and e911 – where is the disconnect?

Wednesday, November 28th, 2007

DSCN0592Google Maps for Mobile will soon include a GPS-like ability to find your current location.  A little while ago Gizmondo wrote about an iPhone hack that allows almost, but not quite GPS functionality.  The hack itself sounds a lot like the way phase II of the wireless E911 service works, and my guess is that Google Maps is fairly similar.

If you take a look at this map, you can see than many states have > 80% deployment.  On the FCC site you can find reports of the e911 deployments completed by cell phone companies.  Any company that doesn’t have over 95% of their customers with E911 capable handsets is currently getting fined.  So it’s a shame that Google and random iPhone hackers have to reimplement all this.

I’ve never worked on E911 support (or anything cellular, for that matter), but it seems to me there is an incredible opportunity here.  One of the great things about the iPhone is that it drives adoption of data plans.  How about including psuedo-GPS capability in nearly every phone as soon as you sign up for a data plan?  That would be a huge incentive.

Here’s an even more radical idea:  why not come up with a standard way to communicate presence and location data so users can do things like local search?  It might take use years and millions of dollars to develop proprietary systems to do this, but if we use an open standard perhaps this could be adopted as quickly as things like the web and email.

Even better, operating under an open standard will allow geeks in garages all over the world to develop new social software systems we can’t even dream of.

The importance of design – Can you read this at 60 MPH?

Tuesday, November 27th, 2007

The New York Times had a great article a few months ago about redesigning the font used on highway signs.  You’ve probably seen the current font, Highway Gothic, a million times without ever thinking about it – it’s been in use for more than 50 years.

Granphic from the New York TimesWorrying about the font on the signs seems pretty silly compared to all the engineering and resources that go into a single bridge, let alone the entire highway system.  Why does this merit an article in the Times and what does this have to do with programing, web development, social software, or any of the topics many visitors to this blog are interested in?

Programmers and analysts sometimes doubt the value of design.  It’s hard work gathering all the requirements and writing all the code – we don’t have time to worry about how pretty it looks.  A lot of projects we work on, though, involve creating user interfaces, often web applications.  That means that, when it comes down to it, your job is to support the user’s tasks.

Now if someone wanted to add 10% to your hours to pick just the right shade of chartruse, you would be justifiably miffed.  But good interface designers will have good, empirically-tested reasons for their work and the guidelines they live by.  Highway signs are a great example of this kind of empirical benefit:

Intrigued by the early positive results, the researchers took the prototype out onto the test track. Drivers recruited from the nearby town of State College drove around the mock highway. From the back seat, Pietrucha and Garvey recorded at what distance the subjects could read a pair of highway signs, one printed in Highway Gothic and the other in Clearview. Researchers from 3M came up with the text, made-up names like Dorset and Conyer ? words that were easy to read. In nighttime tests, Clearview showed a 16 percent improvement in recognition over Highway Gothic, meaning drivers traveling at 60 miles per hour would have an extra one to two seconds to make a decision.

A one or two second gain in legibility matters a lot when your life depends on it.  Few web applications present the same kind of physical danger, but multiply a small gain over an application with 10,000 users, operating 24 hours a day for a year, and you can see how this can impact the business.  Good design is part of the larger concept of usability.  As anyone who’s done any usability testing can tell you, most applications have many small, easy-to-change pitfalls that can quickly add up to huge wastes of time and effort.

20 years ago, we had an excuse for bad user interfaces…

Monday, November 19th, 2007

When I was a kid, computers were slow. They had little or no storage, the most reliable connection was sneakernet, and having more than four colors on the screen at the same time was amazing. So the user experience looked a lot like this…

For quite some time now we really haven’t had those same excuses, so why does this video remind you of the point-of-sale system at work, or the database HR is still using, or the software that came with your MP3 player?

How do you set up a PHP development environment?

Saturday, November 10th, 2007

DSCN1377-1Are you a budding web developer wondering where to start?  An old hand looking for new tools?  Let me tell you a little bit about how I do my PHP / web development work, and maybe some it will be of use to you.

I am starting up some work on Mealographer again.  It definitely needs it, I did a usability test about a year ago and still haven’t fixed the issues I uncovered.  I haven’t been doing a lot of work in PHP recently, at my day job is all Java all the time.  I used to be happy with a text editor, a server somewhere and a browser, but since I’ve been using Eclipse I’ve become spoiled by better tools.

So what do you need to get started?  If you just want to play around, all you need is:

A text editor.  You can use Notepad, but I’ve used HTMLKit in the past.  It’s free and it does basic stuff like syntax highlighting nicely.

A server.  You can set everything up on a remote server, many have PHP accounts for as low as $5/month.  Right now I use Site5 [referral link].  I also want to give a shout out to Q5Media, though PHP isn’t their main thing.

A browser.  This is pretty basic, but worth mentioning.  You need Firefox, which is free to download.  You’ll also want to test things in IE, which you probably already had.

You can do real work with just the above.  It’s worth taking advantage of all the great tools out there, though, including:

An integrated development environment (IDE) – I’m pretty happy with Eclipse for Java development (or the related IBM RAD 6).  What about for PHP?  Right now I’m trying to decide between PHPEclispe and the PDT plugin.  Anyone have an opinion on which way to go?

A local development server – If you want to run PHP locally on windows, you can install Apache or get PHP working on IIS.  In my experience, though, you can’t beat WAMPSERVER – it includes Apache, MySQL and PHP and makes configuration pretty easy.

Source control – There’s no way to keep track of a project of any real size without a change management system.  I have used CVS a lot, and SmartCVS is a good free client.  There are also CVS plugins for Eclipse.  I have heard a lot of good things about Subversion as well.

Web developer plugins for Firefox – seriously, if you don’t have these, you might as well tie your hand behind your back when writing JavaScript of CSS.  Here’s a good list of Firefox plugins.

So that’s what I use – what am I missing?  Post suggestions in the comments below.

Video Presentation on Tagging and Folksonomies

Wednesday, November 7th, 2007

Here’s the video of a presentation I gave at the Cleveland Web Standards Association last month (at the time of this posting the website is a little bare, check out the Meetup page for more details).

In this video I talk about the same topic as myTagging and Folksonomy article in the ASIST Bulletin. What are the different kinds of uses for social tagging and folksonomies and what are users’ motivations for tagging?

Jason Morrison – Tagging Systems & Folksonomies from Cleveland Web Standards on Vimeo.

I’m pretty happy to have been the next presenter after Eric Meyer. In this month’s meeting Brad Colbow talked about CSS positioning.What do you think? Feel free to leave a comment below.

New WordPress plugin available – put tag clouds everywhere with Altocumulus

Tuesday, November 6th, 2007

If you’ve gone to any of my Category pages on this blog (my Academic papers, for example), you might have noticed I have a tag cloud with just the tags related to that category.  After I figured out how to do it I packaged it into a WordPress Plugin, called Altocumulus.

This goes along with my research interests into folksonomies and information retrieval.  I haven’t had the chance to study tag clouds empirically but my guess is that one giant tag cloud for an entire web site or blog might be more cool looking that useful for navigation.  I think that making use of tag relationships a bit more might show the strength of folksonomies for navigation.  So now, if you click to see my design pages, you can see the kinds of topics my designs cover.

For another example of this in action, take a look at Unsought Input, for example the Innovation page.

Go ahead and download version 0.1 now.   It requires WordPress 2.3 or higher.  This is my first WordPress plugin so I’m sure I’ll figure out ways to make it better over time.  If you have any bugs, pointers, or suggestions please leave them in the comments below.

Tagging and Folksonomy artcle in the ASIST Bulletin

Sunday, November 4th, 2007

Walking to the overlook  The issue has been our for a little while now, but I thought I would note that I have an article about The use of tagging systems in this month’s issue of the ASIST Bulletin. Take a look at Why Are They Tagging, and Why Do We Want
Them To?

Almost everyone has a tagging system the web is facing serious weather with tag clouds on every site. I think it’s interesting to explore the uses of folksonomies and why users bother tagging things in the first place. Here’s an excerpt:

When thinking about adding tagging to a site, the first question should be: What do we want to get out of this? Does the site need something to improve search results or a new navigational facet to better connect related pages? Is the goal to classify lots of multimedia objects with minimal cost or to get users to interact with the site a little more?
