Cookies in Feed Readers

We have to get cookies in feed readers. Why? Because we’ve got to be able to intelligently serve ads in feeds. And it will also allow publishers/bloggers to see much more about their audiences than they can now.

Jeff Jarvis and I talked about this yesterday.

And today Chevsky said the same thing in a comment to my last post.

I agree with both of them.

Does anyone know of any feed readers that support cookies right now?
