I'm sorry to say that I don't think the weekly feature which is on the NewsBusters right sidebar (NewsBusted with comedienne Jody Miller) is all that funny.
Nevertheless, I still find Newsbusters itself a great (and much-needed source) for reporting on the reporters. Media bias is no myth -- and everyday Newsbusters offers plenty of evidence to prove the point.
Lachlan Markay has an interesting post over there today that I'm recommending in particular. It deals with conservative books and their dominance of the best-seller lists. Check it out and browse through the site a bit. I think you'll see it well deserves a "Bookmark" on your list.
And who knows, you might find Jody's jokes more entertaining than I do.
