The timeout between multiple postings seems now to be much larger than before. I've run into it a few times when trying to reply in different threads. Did this get set to something like 5 minutes, and could it be lowered? I presume it used to be different, since I don't remember seeing it before the reset.
An additional annoyance is that it blocks seeing the preview for a post entirely during the cooldown period.
