Disclaimer: I have not done this, I'm too busy focusing on other projects, but I'm quite positive that it will work. What does everyone and their mother want right now? Google Wave invites. Can you say Google Wave + BHCB/WP Guardian +CPA = $$$? One way to promote it: Google Wave trends all the time on Twitter and there are a lot of people on there searching for invites. Just find some 3rd party auto-tweet service like social oomph or something similar, where you can set up a week or month's worth of tweets at a time. Make every 5th tweet something like "I got a few Google Wave invites left, get 'em here... bit.ly/whatever" (You can use stupid quotes or anything dumb for the other tweets). Obviously the bit.ly link leads to your site where you have BHCB/WPG blocking a page that says "sorry, we're out of invites, check back soon" or something similar. A nice CPA offer for Google Android would be good for them to unlock the invite. Of course, you could always just lead them to a page that says "Enter your email address here, and an invite will be sent to you. (It usually takes a few days to get the invite, they're backed up at Google.)" Use your imagination to fill in the blanks for this option. Hope someone can take this and run with it.
