Update: The proper way to take down a diary like this is for those who have recommended it, to go UN-recommend it. That way we don't get a corpse diary in the rec list. Please unrecommend and make room for new content!
From here [and elsewhere] it appears that DailyKos does not currently permit users to post comments. The most recent comments are timestamped 8:40 AM EST or so. The OpenThread is empty, and Cheers 'n Jeers is eerily silent.
And yet new diaries appear, and users seem able to recommend them. So I am trying a little experiment, which might provide helpful information to the site masters...
...If you are experiencing the same symptoms, of course you can't say so with a comment. Check the Recommend list here, and if it has not reached ten recommendations, and you see these symptoms, please recommend. Don't take it above that -- this doesn't belong on the list.
Oh, and one more experiment in the poll.
Update: A handful of poll recipients report that they are able to post comments. I assume they are just messin' with our heads, but if not: we can't see those comments that you post, you should post a diary describing your successful comment-posting.
