Alexa rankings come from people who have the Alexa toolbar installed on their computer. I would say it's somewhat biased: Info comes from people who are prepared to install spyware on their computers, and I think results also tend to be biased towards internet marketing sites.

Yes, MySpace and Facebook are good if you want to market and promote an affiliate product or site because you can choose target market demographic like: gender, location, interests, etc.

Don't worry bout which is "the Best" all those mentioned are great because the have millions of registered useres. Thing to do is get on one at a time and participate in the community and work it little by little. You'll get results from how ever many you want to.
