Folksonomies are not hierarchical, meaning they lack the “Broader Term, Narrower Term, Related Term” structure often seen in taxonomies. Also, because they do not use a controlled vocabulary, terms can change quickly, there can be multiple tags for the same concept (library, libraries), and the same tag may be used for different concepts (try searching “cookies” in del.icio.us…).
In the past few weeks, we’ve already explored a few sites – Flicker and LibraryThing to name two –that allow users to take advantage of tagging and in Week 3 many even used a common tag (U32things or vermonteacherslearn) to create an association between photos that we individually uploaded. This week, in addition to exploring Technorati tagging, we will also take a look at a popular social bookmarking site called del.icio.us (http://del.icio.us).
Del.icio.us is a web-based social bookmarking (social bookmarking = the open sharing of links) manager which allows you to bookmark a web page and add tags to categorize the bookmarks. It’s sort of like the “Bookmarks” or “Favorites” folders in Firefox or Internet Explorer. Only better. With del.icio.us, you never have to remember which computer you saved the link on. This is ideal for anyone who uses more than one computer. By the way, this includes students using the internet who don’t own a computer at home. Helping them set up a del.icio.us account would give them a way to consistently access their favorite websites.
Many users find that the real power of del.icio.us is in the social network aspect, which allows you to see how other users have tagged similar links and also discover other websites that may be of interest to you. You can think of it as peering into another users’ filing cabinet, but with this powerful bookmarking tool each user’s filing cabinet helps to build an expansive knowledge network. As bookmarks are added and tagged, a folksonomy emerges. Clicking a tag in del.icio.us shows you all the bookmarks with that tag. And in the same way that using a subject heading can narrow a catalogue search, using a folksonomy tag can save you from sorting through 2 million Google hits by showing you what other people have found useful on that topic.
For this Thing, you are asked to take a look at del.icio.us and learn about this popular bookmarking tool.
Resources:
- Otter Group del.icio.us tutorial (8 min video)
- Us.ef.ul: A beginners guide to del.icio.us
Exercises:
1. View the 8 minute del.icio.us tutorial to get a good overview of its features.
2. Search del.icio.us for something you’re interested in. Check out some of the tags people have used for that topic. Try the same search in Google or another Internet search engine. In your blog, tell us what you thought. How do the results compare? Were there any that you didn’t expect? Did you find any tags that were confusing or especially useful?
3. Set up an account on del.icio.us. Add a few websites and add your own tags to each of your links. If you like del.icio.us and want to easily add bookmarks to your account, you can put buttons on your browser toolbar. Instructions are available for Internet Explorer and Firefox. Add a link to your del.icio.us account to your blog. You might even want to explore del.icio.us’ latest addition, a network badge.
4. Take a look around del.icio.us using the U32’s del.icio.us page that was created for this exercise. Note: In this account you will find lots of resources that have been highlighted or used throughout the course of the Learning 2.0 program. You can keep up to date with that’s added by subscribing to the RSS feed.
5. Create a blog post about your experience and thoughts about this tool. How can teachers or students take advantage of social bookmarking sites? Can you see the potential of this tool for research assistance? Or just as an easy way to create bookmarks that can be accessed from anywhere?
Would you like to read more about del.icio.us and other social bookmarking tools? Go to U32’s del.icio.us page and look for entries under the tag headings “del.icio.us” and “bookmarking.”

Further Exploration (optional!)
While del.icio.us may be the most well known social bookmarking service, it is not alone. Several other services, such as Ma.gnolia, Reddit, Stumble Upon, Digg, and Simpy, provide different options for your social bookmarking needs. Look into some of these alternatives and see how they might better serve you or our students.
