Update (1/11/11): I decided to take down the ads. Disregard this post.
Prepare the flaming torches and pitchforks. I've decided to put ads back on here. I'm barely breaking even at my job, and am looking for another (and hoping for a promotion). As before, it's to help me cover expenses to keep me above water as well as to hopefully upgrade the server.
These ads should be non-intrusive. They're about the same as the Google ads you'd see on various sites so they shouldn't interfere too much with anything. Clicksor (the provider) is reputable, and the income I generated did help me a bit back in 2006 when I desperately needed grocery money. So I see no harm in trying them again.
I hope you all are not too mad at me for doing this. I just need a little more income to help with living expenses, for now.
