I think I originally switched away from the normal Wordpress comment system because so many people were unhappy with it... to some other system...Intense Debate. People didn't like that either. Disqus seems to the biggest one out there.
One problem is that, collectively, my readers have a lot more time to spent on this blog than I do. (Which makes sense -- there's a lot of you guys.) So while I'm off at work, or sleeping, or just out there doing time, comments -- and flags -- start piling up.
I can't ask my freelancers to hang around to moderate comments, and there's no budet to hire a community manager, and nobody else I work with knows anything about virtual worlds and wouldn't be able to moderate the comments even if they were so inclined. If anyone out there wants to volunteer to take this on.
I just raised the number of flags required to send a comment into moderation, to see if that would help. Another option would be to increase the authentication level that Disqus requires, though there are plenty of people who get angry under their real names. :-)
I *do*, very much, encourage folks to start other blogs about OpenSim and about virtual worlds if they don't agree with my take on things.
