Finding Web 2.0 Sites

I just stumbled across this great site that calls itself "The Complete Web 2.0 Directory." I don't know if they have all the Web 2.0 sites, but they sure do have some interesting ones. TuneSquare looks like a really good one for musicians trying to get their music heard. TuneSquare is an online music community where unsigned bands and artists can make some money while listeners from around the world can download their songs for free.

Trivago is another great site, where users can find useful information to help them plan a European vacation. There are reviews from people who have already visited a destination or stayed in the hotel, holiday home, etc., that users are interested in.

One that looks really fun to me is Retroland, where users can talk about and create a virtual scrapbook of things from their childhood. Think platform shoes, Shrinky Dinks, air hockey, and Slinky.
