As most of you know, the more stumbles = more traffic. Well stumbleupon.com is charging $0.5 for each hit they send your way but you can easily get a lot if you just have about 100 stumbles. I am offering $0.3 per stumble. How am I doing that, well I own this forum called: http://www.seo-bb.com We offer a stumble exchange service with an active community of stumbles, and people selling stumbles. It cost about 5BB per stumble but if you don't like to exchange stumbles you can buy 1BB at the rate of $0.06 per BB. We also pay the people stumbling for you, so we are sort of like an exchange service. Contact me if you would like to purchase some stumbles, or just join the forum and purchase the credits there.
