Improved Comment Support

I've improved the comment support today for this site. The first change allows visitors to post a comment without requiring logging in. But to help protect against those evil spammers, I've added a captcha and set up Akismet to help keep the spam low.

I've also made it easier for authenticated users to comment by no longer asking for your name, e-mail address, or website. I plan to pull that information eventually though OpenID -- as long as the user agrees to it, of course.

I've also improved the JavaScript in the comments area. If you haven't posted a comment yet, you'll some nice Ajax and jQuery going on. Nothing fancy, really, just an overall better user experience in my opinion.

If you run into any issues with this site or have a suggestion for a new blog post, just let me know!
