I’ve turned on reCaptcha for registrations. Akismet is working to reduce comment spam without requiring a captcha, so I’m not going to enable it for comments yet.
Anyone using OpenID, please let me know if there are bugs when you attempt to make a comment. Of course, anyone should let me know if there are problems when you attempt to comment– you can do this by emailing me (mortaine, gmail), or by commenting on my LiveJournal or one of my other blogs.
Testing Open ID for you, and it said “We were unable to authenticate your claimed OpenID, however you can continue to post your comment without OpenID.”
