State of the Blog

About one year ago, I started this blog as a place for interesting computer stuff I did so people could learn as I did about new and often undocumented things and how to break them. Even with the very well documented stuff, I still had to figure some implementation details out. I know I had a blast learning and writing about this stuff, but I'd like to address some of the more meta things about this blog in this post. I try to keep it to one meta post a year, and this is it for this year.
