Another day, another We Are Media Toolbox challenge!

Today's topic is social bookmarking.  When I first heard that phrase, it conjured up images of women reading their favorite passages from Nicholas Sparks novels aloud to one another while drinking white wine.

How wrong was I? Social bookmarking is now part of my everyday online experience.  I use Delicious -- thanks for getting rid of all those goofy periods Yahoo! -- to keep track of articles and blog posts I may want to come back to.  I search Delicious to find information about topics I'm interested in.  I keep track of what other people tag with "NTEN" in Delicious, as well. 

I haven't gone the extra step of building community around my tags.  Have you?  What social bookmarking site do you prefer, and why?  Share with us in comments, below, or on the wiki.
