I've decided to keep my stance as being against it, as I must agree with Reigando said, as many people do double post, causing more congestion that it's supposed to stop.
It honestly does seem to cause it more, than stop, and it's actually more, I wouldn't say annoying, but more... chunky, if you will, in terms of the wall of text I see when multiple people double post, due to being in the auto-changed channel, then switching to the main channel.
