Some blog visitors haven't been able to view recent comments. I've let TypePad support know about the problem. Hopefully it will be temporary.
The new commenting feature, TypePad Connect, is in "beta" mode, so it isn't glitch free. This blog, like others that have adopted it, are helping to make TypePad Connect better by pointing out problems.
On this front, I've turned off the photo/image that can appear with a comment. I don't like how the space for a comment is reduced by the width of the photo/image.
