Get Paid To Post In Forums?

This could be an interesting one to watch.

I recently discovered an online business, SEO and programming forum that claims to pay people for adding to the discussions. I'm not sure how the apparently benevolent owners are financing this, or even if it will work out long term, but there must be method in the madness somewhere.

There could be many other forums like it I imagine, but you can check out the one I discovered at www.office.us
