At the end of the year, I noticed a few threads in my blog. Namely tech articles, but a few categories I want to keep following: Books, Art, and Music.
So I'm creating those buckets through tags.
Several blogs have them, but it's Rach Smith's use of a few main themes that inspired me.
I've heard somewhere that tags largely are more for the author than the reader. How often a visitor filters by tags (or even digs deep in the archive, as Alan Jacobs noted) is pretty minimal.
I think there's still value in saying "Hey, I write about this stuff, here are some thoughts on these things."
But I'll agree, probably it's more for me! When I have a bucket, I like filling it. So, keeping Art and Music buckets will lend to more long term thoughts in those categories, even if this space is largely for technical articles.
Besides, I like the colors.
