Saturday morning's idle question

If you're reader of this blog (by which I mean either Eagles Over the Kennebec, on LJ, or The Blog Without a Name, at sharonleewriter.com), you obviously read at least one author's blog.

My question to you today is:  Why?

Why do you read writer's blogs?

. . .and, Special Bonus Question:

Of the author blogs that you do read, which is your favorite -- and why?

Have at it.
