Maybe it's just a weekend thing, but moderation currently isn't happening!
It seems things are set so that posts with links in them get moderated, others don't. I made a post with a bunch of links, and it hasn't shown up.
I was able to update an error I made in the post, by following the link in the "your post needs moderation" link. And then I got an email that it was approved... but... it's still in moderation. (maybe the original was approved, and now the changed version needs moderation...)
I guess the author can see/edit the post while in moderation, but the only way to get to it is from the link provided in the email.
Anyway, here's a link to that post, which might be useful if it's just a one-off problem:
