Minor blog changes

I've enabled a couple features introduced by Blogger over the past 6-12 months -- comments and backlinks. Comments are configured to allow anybody to post, but I've turned on word verification (aka captcha). I've heard read too many stories about comment spam hitting blogs -- even blogs with low traffic like this one. If you don't like it, don't comment.

You're always free to send email to me, though. (image created at http://services.nexodyne.com/email/)
