I am Going to Start a Social Networking Site.?

[Cyberma]

Be wise like Mark Zuckerberg does. He used his friends and money to put up Facebook. In your case,you'll need to prove people first that you have a good and responsive social networking site before even think about adverts. If you're became successful for that, adverts will then follow naturally. Lot's of businesses will ask you to put their business's presence to your site.
