Cleanup of tags and categories.

One of the things I need to do soon (and after that, on a regular basis) is to make sure all of the articles on the U60 blog have good tags and categories.

This is here mainly as a reminder to myself, but I'm going to start separating the categories, especially since about 90% of the articles on this site are in both the "Life" and "Technology" categories -- I'm going to work on separating those a bit better.

I may also replace or rename the Observations category.

So far, I've been doing a good job with the tags on this blog I think, so I need to go back and give tags to some of the posts that don't have them, and I need to continue the decent job I've been doing with the tags.

So yeah, just some thoughts about the blog.
