I didn't leap to conclusions: I noted that the site worked fine on IE7 until very recently, which suggests that IE7 is not the problem. It's a datapoint that you still don't seem to have accounted for, considering that you're taking its performance on other browsers to be relevant to the matter of why LW stopped working at a specific time on (at least) one browser.
(Note: as I am involved in this exchange, I'm not modding down anyone's comments, including yours.)
And if you're not downvoting my posts (and this isn't meant as an accusation of lying) I'd like to know why other people are, I don't see anything fallacious about them.
Edit: Perhaps it's because I started writing a sentence, went off to write something else, and forgot to come back and finish it. I'll go change that. :-)
I can't see the comments under posts anymore. This just started happening in the last day or so. (If I know a comment is there, I can still see it in the "recent comments" section.) I'm using IE8 at work (CORRECTION: IE7), where a lot of stuff is blocked for security reasons, but not in a way that kept me from seeing comments until recently.
What changes were recently made to the site that would cause this? It would be really nice to undo those.
Btw, I won't be able to see the replies to this post unless I find them under "recent comments", so ... if you want more specifics about how it looks on my end, you'll probably have to PM me.
