LibriVox: A wonderful site creating free audiobooks of public domain literature.
And a link to the Librivox Forums where people can volunteer in various capacities.
See also my page of recordings I've done and am working on for LibriVox. The link is above.
Ravelry: A social networking site for fibre artists. Also has great organizational tools to keep your projects and stash in order.
(fibre arts: knitting, crochet, spinning, dyeing, etc)
The L-space Library: A great site for all things Pratchett and Discworld.
Paul Kidby's website: The artist who took over the Discworld illustrations after Josh Kirby's death.
French/English Dictionary: A pretty good online resource. French-English, English-French.
The Internet Movie Database: Info on all things tv and movies.
I add new links every so often, when I come across interesting sites.
