Enabling Google AdSense in RSS

Google are trialing enabling AdSense in RSS with FeedBurner already implenting support for this feature. Adverts in RSS, everyone knew this was coming though is it good or bad? My opinion at the moment is bad. You should only see adverts when and if you decide to goto the site and read the content. Upto that point your feed is an advert for your site to intice the reader to visit. At the moment the only objection to this rule that i can see is if your feed contains the complete message/post i.e. They gain nothing extra than graphics by coming to the site.[Via]
