Need some inspiration?

I recently came across this post by Darren Barefoot which includes 55 blog topic ideas. I've decided to start using some of those ideas, and everyone else is welcome to do it as well. I was going to do one every day (or every other day, or whenever I have time) but I realized you can't really write about all of them because some are contradictory. So I'm just going to start at the top and write about the ones I feel like. I think some of them are going to be very interesting.
