If you point the errors out to us, we try to get them fixed.
If we don't know something's wrong, we can't fix it; so we work on doing other things with the site (like our new Mozilla search plugin).
We don't aim to be wrong, but there's a lot of porn out there to keep track of, and not a big staff to do it; so if you see errors, drop us an e-mail so we can get into the processing queue.
... back to lurking...
