Been experimenting with some fun stuff on the site, as you may or may not have noticed. First I've enabled comments, but you have to solve a CAPTCHA. Instead of a normal CAPTCHA though, I'm using a reCAPTCHA. The difference is pretty cool though. Instead of just solving a bunch of jumbled letters, you're actually helping to digitize books by "reading" words that OCR software couldn't solve. Pretty cool! Secondly, I've made my permalinks a little prettier. I'm considering changing my domain name too. Now that you can comment, let me know if you like this domain or www.xaero.org!
