I've had a couple of blogs before on random subjects, and they usually end up being that type of blog that's updated a lot, then once in a while, then not at all, then a few times, and finally never again. I've never had a blog to myself though, where I wasn't blogging about a particular subject, so this is my experiment.
In general, I find blogging self-aggrandizing. I don't think you can really write a blog without thinking, "Hey, I am just so full of great ideas, read them you jerk and maybe you will improve yourself." Slight exaggeration there, but not much. So if nothing else, here's to successful self-promotion and extensive patting of myself on the back.
