Facebook, Myspace, Bebo… you know what these are. But have you ever thought about making money with them?
If you have a large amount of friends on your profile, you have the ability to send messages and bulletins to all of your friends. People will pay you to send messages to your ‘friends’, things like promoting a new site or affiliate program.
DigitalPoint forums are a great place to find this sort of activity. Some people do nothing but set up accounts, add everyone they can find to their friends list, then sell the profile at a later date for a few bucks. Not exactly being a good friend, but it *does* help raise a few bucks and more often than not, these sites themselves spam you with stuff you don’t want to see, so your friends are probably used to it. Quite often you’ll see people selling accounts boasting 10,000+ ‘friends’.
If you use stumbleupon.com or digg.com, you can also make money for using your accounts. Check out subvertandprofit for more info.
There’s also a site called piqq.us (formerly diggboss) which basically allows you to build up diggs and stumbles for a rainy day in return for digging and stumbling other people’s links. A little unethical perhaps, but now you know why all of those seemingly ordinary/average articles somehow make their way on to the digg frontpage
