Yes or No: Does RSS does drive traffic back?

Steve Gillmor highlights Pamela Parker’s story on reports on Feedburner research that says click-through rates from RSS driving traffic back to sites is going down.
Of course, the elephant in the room here is that Feedburner CEO Dick Costolo doesn’t make a distinction between full feeds (which newspapers, for example, rarely provide) and others, like bloggers, who often offer full feeds (as I do.)
Kinda makes a difference doncha think?
