Delicious

Delicious is an interesting tool that I actually thing will help in my thesis research.  I believe Sarah blogged that it felt a little intrusive to use other's bookmarks, but it is helpful!  I like that you can create idea lists (like vacation destinations or even recipes to use in the future).  I really like that you can follow your favorite user's bookmarking (like Diane Ravitch :).  Overall, I think it's a great tool that I will continue to use even after the class if over!
