My favorite site is, uhhhh, bush-music.com because it has tons of gorgeous pictures of Gwen and Gavin. I also like nodoubt.com because Gwen posts sometimes. Sanrio.com has Hello Kitty stuff. Gothamist.com is a blog that comments on current events and entertainment news: interesting opinions & etc.. Dictionary.com has Roget's Thesaurus online, which is wonderful.
Those are my favorite sites, currently,
