Thoughts on Blog Usability

Blog, Usability, , , , , , , , , ,

DSC_0723 I’ve been kicking around the idea of redesigning my homepage and blog, though I’m not sure I really have the free time to do it. To start, I thought I would to put down a few thoughts about applying usability principles when designing blogs.

When you starting thinking about usability it’s temping to jump right into lists of principles and rules of thumb. It’s a little silly applying Fitt’s Law when you haven’t even established what you want your site to accomplish in the first place. So what, generally, do you want your blog to do?

Personal Goals

  • Share thoughts and work with others
  • Collect a body of work to represent myself (like a portfolio)
  • Collect information for later discovery (by myself and others)
  • Provide an outlet to continue practice writing
  • Allow others to communicate with me and comment

If you’re creating or redesigning a blog for a company, the goal set may be very different. Below are some examples that don’t actually apply in my case.

Business goals

  • Communicate with customers
  • Build long term relationships with customers
  • Produce quality content to drive search traffic
  • Generate revenue through advertising
  • Etc.

Many projects don’t even get this far before the graphic designers and web developers are already making mock-ups, but we still have one more important step to do. We know why you’re building a blog, but why are users coming to it?

Scientific proof that Reddit should add a tagging system

Blog, Uncategorized, , , , , , , ,

First, a disclaimer: the title of this post is obviously exaggerated. Proof is an awfully big word to throw around, and although I employed pretty good experiment design practices and statistical checks, I can’t really prove that Reddit should do this or that. But I can show that what they are doing now is not working, at least when it comes to search.

So, I got an email the other day letting me know that my article, Tagging and Searching: Search Retrieval Effectiveness of Folkonsomies on the World Wide Web, is being published in the July 2008 issue of Information Processing and Management (here’s the official DOI link to the article). In the study I compared search performance between traditional search engines (like Google), subject directories (like Open Directory), and social bookmarking systems (like Reddit) and their folksonomies.

What’s a folksonomy? The word is a play on the term taxonomy – a taxonomy is a system of organizing and categorizing things, like the Dewey Decimal System. Taxonomies usually follow very strict rules and are controlled by experts. A folksonomy is a system of organization built by large numbers of regular users, who add things to the collection, evaluate them, and usually tag them with keywords.

In my study, the social bookmarking systems with tagging systems did surprisingly well – Del.icio.us was more precise than Open Directory, and at a cut off of 20 results it’s precision was fairly close to that of the search engines.

Reddit, however, did not fare so well. It consistently had the lowest precision, meaning that searches returned very few relevant results. There could be many reasons for this, but the biggest difference between Reddit and the others is the lack of tags.

Now, it’s possible that the folks at Reddit have no interest in search, or information retrieval in general. I think Reddit is very effective at bringing out new and interesting links on a daily basis and encouraging commentary (just my opinion, no stats to back that up). But I think it’s a big missed opportunity not to add tagging and see where it leads.

(One last disclaimer: this post is my personal opinion as someone who enjoys using Reddit and does not reflect on my employer. This post refers to research done independently as a grad student.)

Tagging and Folksonomy artcle in the ASIST Bulletin

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?
