I have enabled Akismet a couple of weeks ago. But, since then, nobody has spammed this blog with any comment linking to viagra, pornos, replica watches, etc.
I am a bit disappointed, as I’d like to see Akismet in action.
In the past, I had to install a CAPTCHA plugin as the blog was getting a huge amount of crap. At some point, I even decided to turn off comments for post.

– updated: Got 10 comments as of March 10. They were all spam and Akismet caught all of them but one. Great, 90% efficency so far!
