Glad (sort of) to hear this isn't just my problem ;^)
I also sent an email to Scott/webmaster about this problem at about 930am EDT today. It started late yesterday, I think.

Edit:
Had no problem posting this comment!! May be fixed! Thanks, Scott!

OK. I think we have this issue resolved.

We're looking into it now Temlakos.

This happened to me, too. It took so long that I clicked "add" again, so I accidentally posted a comment twice and had to delete one. I thought it was because I was on mobile.

I'm seeing some real issues starting this morning. I had a long delay in posting a response. I've also followed links on the right and gotten pages with no comments on them.

That happened here, and when I came directly, I only saw one comment although it was marked as having 5.

I am using Google Chrome on Vista.

Let's see how this one does.

Same here... I've attempted to add a comment, and ultimately the browser times-out. From the "Recent Comments" area to the right, it appears that the posts are being registered, but I don't see them on the comment page.

I had the same problem. I just sent a message to Scott about this.
