Social networking is huge. Did you know that some social networking sites are businesses in themselves? Yuwie.com and DirectMatches.com are two fine examples. Sure, there are lots of spammers, but (if used correctly) these sites can get you some referrals.
They can also become their own income streams as well if your downlines are large enough. Can you ever have too many income streams? Of course not.
