You can also pay $0.05 per visitor. The trick is to make sure your site is immediately appealing, otherwise the user will just click "stumble" and go on to the next site.
pretty much. There's no "front page" to get to on stumble upon. Every person who thumbs the site up essentially forwards the stumbled page to everyone on their friends list. Interesting sites propagate through stumble upon very quickly.
Yea my last site got "stumbled" a bunch of times. Serious amount of traffic but I read that you really are only getting half of what your stats say because of how the software works. Not sure. Still good though.
