There are Web 2.0 websites that are dedicated to nothing BUT social networking. One of the better known ones among the younger set is MySpace but there are at least a hundred different social networking sites on the internet and probably a lot more that that.
Web 2.0 social networking sites are divided in many different ways.
There are social networking sites that are dedicated to specific ethnicities; BlackPlanet.com is for African Americans, Babbello is for Australian teenagers, FaceBox is for European young adults, Gronco.net is for Poland, iWiW is for Hungary, Migente.com is for Latinos, Mixi is for Japan are just a few examples.
Social networking sites are also divided sometimes by interests. For example you can find such social networking sites as CarDomain for car enthusiasts, Flickr for photo sharing, Gaia for gamers, Gopets for virtual pets, Joga Bonita for football or soccer, or Last.fm for music.
These are only a very few example. There are a great many more.
Most social networking sites, however, are not dedicated to a specific group. They are general membership sites and the members themselves divide themselves into appropriate groups according to interests and compatibility.
