RSS with advertising in the feeds - the backlash begins?

Those who have paid attention (yeah, all three of you) to what I think
about RSS feeds with advertising in them, know that I've been saying that people will dump the feeds once it starts to bug them since forever, and proclaim so loud and clear in that e-book Unleash the power of RSS. RSS feeds are ads most of the time. It's usually headline + link, or headline + lead-in + link - in effect "advertising" whats new on site X. Some sites spend everything they have in their feeds, their entire post and images - these are the ones most likely to do RSS-ads.
I noticed the other day that Moonhouse beta was complaining that some feedster keyword feeds that he subscribes to were suddenly updated with only ads. Previously, the feeds would have a regular update, and on occasion an ad would appear sandwiched between the regular news - but all of a sudden he had four updates that were nothing but ads. Lets hope that was a bug. Then I stumbled over Dave Winer complaining about BoingBoings feed, as he had received the same advert seventeen times and had enough. He unsubscribed, as one would.

But as with everything new, porn arrives on the bleeding edge first and advertisers soon follow.
What got the Pentdego blogs google account closed in October 2004, put the Longhorn blog in the news spotlight april 2005 - google adsense ads in their RSS feeds. Even now you'll see sites announcing that they have begun running ads in feeds like, Rocketinfo who uses Kanoodle.com as their ad supplier. But many more sites simply put ads in their feeds without issuing press releases about it - it's so easy to do with Feedburner who offer Google adsense ads within feeds.
From Keeping It Really Simple in the Hartfort Courant last week.

RSS has not gone unnoticed by another community: advertisers. A recent Forrester Research survey found 57 percent of the marketers they polled had an interest in pursuing RSS as an advertising channel. But it's uncertain whether Net surfers will accept RSS advertising. Swartz never intended the technology for marketing and doubts others will tolerate it.

"I think the users will revolt," he says. "The whole process of reading is interrupted. If RSS writers insist on putting it in, RSS readers will start taking it out. It's that simple."

I know that ads in feeds have made me unsubscribe - but everyone won't react like I do. The question is, how long will this 'virgin' territory be relativly ad-free? Five more minutes? What do you think?

Oh and as you know you can get RSS feeds of nearly everything on this site, comments, news films, ratings, individual users.... etc.

Update Sept 27: Looks like someone has built a better mousetrap!
Newsfire blocks ads in RSS feeds. I spotted this over at Nial Kennedy's blog in a September 12 posting.
