I need to write a paper on the future of social networking. Does anyone have an interesting opinion or website on where you think social networking is headed?

Its hard to say, it's a trendy business. It will follow only two guidelines:

1.) Whatever the people demand, the sites will offer...

2.) Whatever can be made profitable the sites will offer...

See how myspace evolved to be more like Facebook after that was the obvious public choice. See what types of advertisements and games are available via social networking, and who controls them. How much is based on public opinion (polls and consumer type reports) and how much is based on marketing. You will find that some advertisers have certain content requirements and bans...

Good Luck.
