A reader pointed out a few days ago that he was getting certificate errors and site warnings when he visited my site. I tracked the problem down to a Drupal module that provides the "like" and "+1" widgets for a number of posts, and deactivated it. However, I am re-activating it in order to try to help troubleshoot the issue for the module developer.
This means that for a while when you visit this site your browser might tell you OH MY GOD THIS SITE HAS A PROBLEM BEWARE OR YOU'LL CATCH A VIRUS AND DIE which is a reasonable thing for a browser to report, but is probably not what will actually happen. Please bear with me for a few days.
Update: The problem was patched, and everything should be working again. If you're getting certificate warnings, please let me know, because it's for something new.
