TDavid is having some major issues with TypePad and commenting in that TP won't accept TD's url http://www.makeyougohmm.com.

I know that there are a few who've emailed me to say that they can't comment on my blog, so I just change the filters in MT Blacklist, and life gets better.

I know that not everyone's a tech-savvy geek, but I believe that this adds fuel to the case for why you should use Movable Type vs. TypePad. MT is largely under your control, including how you handle comments and who's comments are accepted, where as TP, being a hosted service, is out of your hands, for the most part.

I'm going to keep an eye on TD's blog thread. I'm really interested to see how this turns out.
