For Web. 2.0 lovers here is a fantastic Web directory to browse, pick and choose.
I have taken a tour of Vidipedia (free video encyclopedia anyone can edit), put my name down for Dandelife (a social biography network) and Quizlet (a tool for learning vocabulary) and will see if I can contribute with some quotes to Quotiki..
Not in the directory yet, but riding the social networking wave, Ben and Dave from Elgg launch Explode, which I have also joined. Aaron did a quicker and finer job reviewing it though so much easier to link back to him 
Thanks for mentioning Quotiki.com. We look forward to your contributions. Check out our podcast where we have fun with quotes at http://www.quotiki.com/podcast, maybe one of your quotes will get featured on the show!

Glad you like Dandelife. If there’s every anything I can do to make it a more worthwhile, let me know. It’s a nice little community we’re building together.
Thrive,
