I will be very blunt. I have seen some people already putting ads in their RSS feeds, and because the way they do it I can barely stand to read the content. I just hope Google has really figured this out because at the most I would only want to see one Advertisement on one days worth of content. Why only “once per day” I figure that is probably the number of times I would have visited your site if I found something worthwhile in your feed.
Geek News Central has had full text RSS feeds for as long as I can remember. Sites that I read that have full feeds are higher on my read list because your not wasting my time.
Their are a couple of tech sites that I used to get daily newsletters from, and also used to subscribe to their RSS feed. I have quit reading because your too damn worried about your Google revenue then to put up quality content.
Robert Scoble has a guideline that he goes by and I think I will adopt it here. Same applies with me if I add you to my news reader it is because I want a long term relationship with you. [Scoble]
