My blog has been besieged by spammers for weeks. You haven’t seen this since they haven’t been able to get past registration. Still, getting tons of registrations every day has been annoying to me.
So, I’ve converted the comments system to Disqus which is pretty ubiquitous now. People can also use Facebook as well.
If you had a registered account that you used to comment (couldn’t find any out of the tons of users) your comment has been exported to Disqus and should show up again shortly.
