OpenId comment authentication seems to be extremely hit-or-miss. It works for some, and for others their posts get flagged as spam, and for others still they get swallowed entirely. I’ve tried to debug it, but I haven’t figured out what’s wrong. I tried to deactivate it, but it just made things worse. So until further notice, please don’t use OpenID or your LiveJournal ID to comment on here.
Update: I just remembered that I had to hack the source in order to make this work before, and I recently installed an update. The update probably over-wrote my hack. Now to dig though the backup to see if I can find the hacked file.
