Well, there is a blog for you. The Comics Curmudgeon is a very professional blog dedicated to answering these questions and many others. The site author is very funny with his snarky commentary. But even more entertaining are the outside comment makers. Sometimes there is a trail of 200+ comments.
It can be difficult to follow along as most commenters write in short hand: MW=Mary Worth, GT=Gil Thorpe, DtM=Dennis the Menace, etc. It took me a while to figure all that out. Plus, they frequently comment on comics that I don't read or that aren't carried in the local paper (e.g. Apartment 3G, Archie, They Do It Every Time). But on the whole it's a very clever read.
