You know the one I mean - John Chow vs ShoeMoney. I thought it might have been a good way to promote a feed (with an incentive obviously), but I think it's a good way for anyone to try and promote their RSS Feed within their own posts. I just put it up for download, and you can see how it looks on the page too. It's pretty configurable admin side - CSS styling, and feed templating. Ignore the slightly disgruntled post there if you want lol, download is at the bottom of it. Maybe a novel way to advertise a feed, and of course if you have any improvement suggestions, fire away.
good one to promote feeds...but from title i thought it would be plugin that can add footer to posts only visible to feed readers(to have prizes for feed readers only)..something like feedcast
