I wonder why most blogs have no ads?  We are not shy about recommending things, places, and products on our posts, so why not have ads for the recommended things, places, and products on our blogs?  If it can be done easily and without losing control, bloggers can make money without selling out.

Lets see how this can be done.  A blog crawler can scan the blogspace for recent blog posts containing certain names like "Diet Coke" and "Nokia 7650".  When one is found, an ad-space offer is made to the blogger by e-mail, feedback, or web services.  If the blogger agrees, then the blogging tool inserts the ad automatically.  Expired ads are removed when the time limit ends.

Next problem is how to handle the abusers who posts bogus news containing product names and nothing else.  Use a combination of Google's approach, Bayesian filters, and other statistical abnomally detection techniques.

Last major problem is what to do about RSS feeds and news aggregators.  Links to ads can be included in RSS feeds and news aggregators should allocate areas to display required or optional ads.  Detecting new feed clients that do not display mandatory ads will be difficult but manageable.
