Problem with posting on Steve's blog

I hope this is the right forum for such a thread.

I’ve noticed that when trying to respond to two separate blogposts at www.thelinguist.blogs.com, for some reason both my posts disappear some time after posting them. Is anyone else having this problem? I’ve tried this on several PCs on both Firefox and Opera, but to no avail.

Odd, it all seems to have come right now.
