Have you tried the new Blogger?

I chose Blogger as my publishing platform a couple years ago for several reasons, but one thing that has been noticeably absent compared to other popular alternatives is being able to categorize my posts. I finally moved to Blogger beta this weekend (one of the smoothest migrations I've ever seen) where they now support post "labels" to help filter by topic as well as chronologically. Now with one of the top items on my wish list granted, I will gradually be adding appropriate labels for my old posts.

In the meantime, if you've been debating how and when to start blogging yourself, just start doing it.
