The site appears to be a bit constipated this morning–we’ve had issues with server errors, and some have made repeat posts. There are presently entries in the comment queue which TypePad thinks are published, but which don’t appear to be visible on the web.
If you see “Server Error”, chances are your post will show up sooner or later. If it doesn’t, feel free to ask. I can be reached at gmail (my name @gmail.com).
