A couple weeks ago, I discovered something called
Link Feedback. It's a javascript that you insert into your home page, and it will automatically link back to all of your referrers. Today, I installed it in the bottom of this weblog. But it doesn't seem to be working for me. I've seen it work on a lot of other sites, though. So, I'm sure once the guy replies to my email, we'll figure out why it's not working. Hopefully.
