If we did return to post limits as the standard instead of the exception, what do people think it should be?
200.
First, when the limit was 300 new spinoff topics had not only presented themselves, but were midway through development as arguments when the thread was closed.
200 allows 20 people 10 posts or 10 people 20 posts to present their case with regards to the OP. That should be sufficient. Slogging through an old 300 poster is a bit of a struggle and it would be nice if the debates were a little more contained.
