What is the best social networking site? Friendster? Tribe.net? MySpace? What do you use these sites for?

I have a myspace and have friends on it but just got the facebook. However, how do I start adding people from my school without looking like a creep and then run into them on campus. I do want to meet new people but I dont know too many people at my school. I just don’t want to add random people. Transferring to my university from JC makes it harder. I graduated h.s. in 01, before all this social networking craze and not too many people my graduting year are on them. The people I actually talk to in class or at school are not on facebook.

I have something that’s been bugging me for a while now. On sites like MySpace and Friendster if you are on someones page it will tell you if they are within three degrees of them or whatever.How can this be caklculated efficiantly as each user could have 100s of friends? Anyone got any ideas.
Gstoll2003 suggested using Dijkstra but like I said each user could have 100s of friends. How could this be made to be efficient? A graph would have to be constructed every time this was needed to be known. If it each link were a tupul in a database this would be computationally huge. If you were to check three degrees and each user had only 10 friends there would already be in the thousands of queries (or perhaps one huge recursive query).

In this video, I answer yet another question from darkplayer38 who is wondering what in the world is Twitter.

Twitter’s purpose was originally to state “What are you doing?”, but what made Twitter popular is that it has evolved beyond this purpose. It has since become “What’s going on in the world?”. As a …
