I disabled reCaptcha today, and installed the drupal Mollom module.
Normally this would mean that when you are not a spammer, you will not be asked to input a captcha - unless Mollom is unsure about your comment.

I'm looking forward to getting to know Mollom :-)

UPDATE

Mollom seems to work very nice. As I remembered suddenly that I liked the idea of Dag about a warning module I installed and I will keep this site moderated. You never know when a spam slips through...
