RSS Ads done the wrong way!

Bob Wyman: If we are to have advertising in RSS and Atom feeds, advertisers must provide those ads in such a way that they don't break the existing blogging and syndication infrastructure. In particular, once an ad is inserted into a feed, it must not be changed unless the content in which it is embedded is also changed. Not following this rule will result in the duplicate detection code of numerous feed readers incorrectly presenting posts to users when those posts have only had their ads, not their content, updated.

Randy: This sounds like a software problem, not a problem with the ads. Using a simple hash of the <description> to determine uniqueness is pretty much a flawed algorithm. Sounds to me like ads are breaking PubSub.
