Fighting Spam and Digitising Books with reCAPTCHA

When I added a comment form to this blog, I wondered how long it would be before I started getting comment spam. Then I wondered if I was flattering myself to think that spam bots would even be interested in my site.

So it's with mixed emotions that I have to admit that right now the number of spam comments I'm receiving is outstripping the number of genuine comments by a ratio of about 10:1.

The time has come to add a CAPTCHA to the comment form.
