I noticed something odd about this site. After posting a blog entry last night, today I checked "All recent posts" from a different computer (without logging in first), to see if anyone had replied.
Strangely enough, not only had that blog entry, as well as my reply to an earlier one disappeared-- the direct link to it didn't work either, and reply-count on the old entry showed 3 rather than 4-- but so had everyone else's posts since about 18:15 (Mountain time?) yesterday. Well, that was the most recent timestamp showing.
After logging in, everything was completely back to normal, with quite a few new posts from today.
Logging back out, still on the same computer, took me again to the time-capsule view from yesterday evening.
I was on a machine that had never accessed this site before, so client-side caching couldn't have been responsible. I went ahead and emptied browser caches anyway, just to be sure, but as expected that had no effect, and I could still reproduce the problem at will by just logging in and out.
As an exapmle, here's a paste of the top 3 most recent posts, while logged OUT, as of 2:45pm EST: (formatting will probably get mangled:
