Due to the recent surge of comment spam on Nicolas's blog (160+ in 10 days), I've now implemented the most basic captcha I could think of for posting comments in our blogs. FWIW, I used a text input, instead of the simpler alternatives: a checkbox or a dropdown so that it is unlikely to be bypassed "unintentionally" by random content.
I wonder how long it'll take to get some spam again. I hope it will take a while as I think that even this utterly basic system should keep the spam bots away until a spammer investigate this site in particular, and I guess this shouldn't happen anytime soon (given that we only host our own blogs).
