Based on the results we've been getting, I think running 3 Question Polls to get Indicators of Interest and then running Community Auctions is going to be the huge-est opportunity for this year.
You don't need your own audience to get started, and it's easy to make a bunch of money in just a few days once you can find an audience owner to partner with.
I've been updating the training over the break and while there's more to add, there is enough there now for you to get a good idea of what's involved and how to do it to get you started.
Any questions post in the comments and I'll help you out.
Don't sleep on this. It's freaken easy and very cool...
