FeedShare Blog Ad Network

Rojo, the company that helps people discover and consume content, has launched a beta version of FeedShare, an ad-supported feed network designed to increase sites’ feed subscriptions. It works like this: you put Feed Listings (which look like adsense ads) on your site to promote other blogs in the network and in return your blog is promoted on similar sites. For every page view you give the blogger network, you get one back. Rojo likes to think of FeedShare as a powerful Karmic exchange.
Sounds like an old-school pageview-network but if you want more people reading your feed, well why not?
