To follow up: this morning I clicked on the above link, and I see 101 comments. No idea what changed - nothing changed at my end, I'm sure.

And another followup: the problem is now occurring for me in Parker's "All The Way May" article. Clicking on it claims to have only 1 comment, whereas I entered a second comment which I saw show up before I closed the window earlier. Interestingly, if I use the Search tool on the word "Trevor", this thread shows up twice, one claiming 6 comments and one claiming 0. If I click on the one showing 0, I do indeed see a version of the article with 0 comments; if I click on the one claiming 6, I'm back to seeing a version with only 1.
I tried to include a screen shot but the reply system said that was too many bytes.
By the way, I'm still working on this, everyone. I've in the midst of a back-and-forth with the developers about it. I don't think they've seen it before.
