Just installed reCAPTCHA to get rid of spam from comments.

You don’t see, but there was a lot of spam comments on my blog. As I have moderation on, they didn’t appear on the site… but it does not mean that they didn’t appear in my inbox.

So now, reCAPTCHA will help keep my inbox cleaner. As well as your comments will help digitize books.

At least according to Ben Maurer.
