Purpose of my blog

I've recently decided to take a renewed interest in my blog, and have been trying to think of what to write about so that my blog isn't just another pointless use of hard disk overflowing with information that even a friend or relative can't stomach to read through.
The best I can come up with is to post information on projects I do, and things I buy. Granted it is not the most original idea, and maybe I won't always post about those things, but I am in hopes that when I post, someone can either learn from a mistake I make in the process of a project, or get a second opinion on a game, album, or something along those lines. Sometimes Google doesn't have information I'm looking for, so when I figure it out myself I'll post it here and save someone else the struggle. Anyhow, that's the plan, we'll see how it goes!
