I've mentioned this before. Not sure if it was in a post or in comments but the comment timer is really really annoying. 

I log into BBS when I have a few minutes to spare. I'm not the only one who has a busy life to balance. When I log in I want to reply to all the new comments I have and they are often in the same post but I'm constantly hitting the timer and it really tests my patience.

The team have removed all the rewards for spam comments so maybe it's time to remove this annoying timer too and just let us reply to comments without this barrier.
