Are you asking "what's a carnival?" Blawg Review describes the process as:
A blog carnival is a traveling post about a topic or theme . . . Blawg Review has topics discussed by lawyers, law students and law professors. Each weekly issue of Blawg Review is made up of article submissions selected from the best recent law blog posts. The blogger that puts together the Blawg Review carnival each week is called the "host" . . .Check out the past editions of Blawg Review on the right side bar of the Blawg Review blog. This will be my second time hosting -- last year around this same time I hosted Blawg Review #44.
The theme for #44 centered around a tongue and check debate of blogs vs. blawgs vs. bobs. Just in time for my hosting this tidbit in from Kevin at Real Lawyers Have Blogs. Seems the debate continues on whether "blawg" should have a place in the Live Web -- if Wikipedia boots it I'm boot'in it. Leave it to lawyers to allow this to rage on. However, look at Google Trends. It appears that "blawg" is on the upswing.
