Blog comments disappear?

[swarmster]

I've tried commenting on main page articles a couple times this morning, and while my comment appears as usual immediately after submitting it, as soon as I refresh it's gone. I would think commenting is broken, but other comments have shown up in the meantime.

Any ideas as to what's going on? I have a Disqus account that's confirmed, and my comments don't show up in my account 'history' there, either.
