Getting a lot of emails about the comments becoming too unruly. I used to read every comment up until about a month ago, when it began to just kill my inbox. I still flip through them usually but certainly don’t read every discussion.
I don’t know. I like to keep restrictions to a minimum. At first you didn’t need to register to comment here. That got out of hand after a few months, and now I require registration like most sites.
As far as rules: just be respectful. Don’t call people names, don’t insult them personally if you don’t agree with them. Basically, behave like adults. Do you need more than that? Do you want someone policing the comments and bans handed out?
