I’m not a very big fan of Gizmodo, but I found their RSS feed interesting today. Check out the attached photo, which highlights four ad units nicely clustered at the bottom of every post. They’ve got two text ads (one from Pheedo, one from Google) and two Google Image/Video blocks:

I have mixed feelings about this. One the one hand, that’s a lot of ads. On the other hand, they’re tasteful and all clustered together so that you’re clear they are ads. They are compact, and don’t interrupt readers who are reading the feed. So in some sense, they’re an excellent example of how to do RSS feed advertising.
