I have never been a big fan of categorizing my posts.
I do it and I have a few categories but I'd much rather use tags to do the work of slicing and dicing my posts.
I look with envy at the people who use WordPress and the way they can tag their posts with ease.
I don't like the idea that the categories in TypePad have to be defined in advance and that you have to do some work to add a new one. Tagging is much easier and simpler.
So I keep my categories to six. And I have kept them that way for almost two years.
But I did change the name of two categories today.
New Music was changed to My Music. That was long overdue.
Presidential Politics was changed to Politics. I don't post much on politics anymore, but when I do, I don't want to limit my views to the President.
If by chance any of my readers use anything that is driven off specific category names, please make note of this change.
