Ads & RSS!
Above is a link to a site that talks about putting ads in RSS feeds. In my opinion, ads on RSS feeds would not be good. Though it might generate revenues, it creates extra "noise" on the feeds that hinders the traffic. As some people have posted on this site, the feeds will indirectly add to revenues by increasing traffic to your site - meaning no need for ads. In general, I personally dont want ads, pop ups, or text inserts on RSS feeds. Let me know what you think?
