Drowning in a sea of Web 2.0 sites

The number of Web 2.0 websites seems endless. After just signing up on Facebook, I learn about 3 more new social websites: Hulu, StumbleUpon, Pandora, and get reminded of a few that I forgot all about Digg and Lastfm. Many of these sites I have set up accounts and forgot all about them. Some like Picasa and Delicious I find quite useful for building better websites. In particular, Picasa has a handy slideshow feature for integrating cool slideshows in your website without having to learn any complicated code. Facebook is useful that it imports many of my Web 2.0 accounts into one place, the downside is that users have to sign up for a Facebook account to view my imported Web 2.0 profile.
