I disagree. People using RSS readers aren't likely to be "confused" by something like this, and they likely don't care. If they click through, they go to the content. That's all they care about. And what is the point of going to a blog permalink page with a short note and closed comments, just to click a second link to get to the content they're looking for? That seems more "confusing," as well as inconvenient.

Anyway, it works for Daring Fireball.
