Question

I've a question, particularly for my fellow bloggers. I've noticed quite a few bloggers will have a set of links on the sidebar entitled "Best of..." the writings of the blog. My question is: what method is used to come to the best of conclusion? Is it your own opinion, your impression that you've just written a really good piece, or do you gather it from the responses in the comments column, or the links, or some combination? Or is it some other method entirely?
