I’ve done some research on using tags from social bookmarking sites for web search, but I’d like to learn more about other ways in which users might use tags for information retrieval.
Do you use the tags on sites like Stack Overflow for navigation? Do you think of them like filters (narrowing down a large list of questions), or as categories (showing how the site is organized), or something else?
I use them for searching for my stack (C#, ASP.NET, WinForms etc). I have them set up in Launchy as shortcuts.
I have posted some thoughts ideas on my StackOverflow blog post – feel free to comment on there if you like:
