My first gut reaction is: this sounds wrong. I don't understand how you're sending more traffic, although your intentions may be altruistic (solve the major problem of how to get people to test your site out). If you're just trying to convince people you're going to dump traffic on them, I believe those businesses already exist in the form of link/traffic exchange networks. And those are not interesting to me at all.

But if you're saying I can get some more beta testers who won't trash my site, I'm interested. Can you explain how exactly that works in as plain English as possible?
