I blog a lot. I do it mostly when I do a fun hobby project and want to write down what I did. It's kind of like a public journal with some pics. They're usually esoteric enough that when someone searches for the thing I was writing about, they'll find it. I get a few hundred hits on a handful of pages per month. Not going to make it big with this, but it is fun and I just love publishing hobby stuff on the internet for some reason.

I also find it kind of fun when I'm searching for something and my own blog comes up reminding me how I did something 6 years ago.
