Yes, that is correct.
It seems there is a bit of delay in seeing new comments/replies.
I also noticed people complaining that comments they posted to people's walls were not being recorded. In fact that happened to me yesterday. I posted a reply and couldn't find it in the list of replies, so I had to re-post it and then it showed up. So word of warning... make sure your replies actually show up after hitting the POST button.

I just posted a new game day (June 28). Please post your moves there.
