Very few posts get +20, only a rare one gets +30, so demoting an occasional outlier would not be a very onerous task. That said, simply restricting the ability to post to Main will stop those with more ego than common sense.
I think Will meant that some posts didn’t belong in main for reasons other than merit. For instance, Vladimir_Nesov’s latest post was based on a great and original idea, had an excellent exposition, and could easily have broken 20 karma points—but he was airing it for discussion, and he’d probably rather not do a top-level post on the idea until he feels it’s ready for that.

Well, there is a karma threshold.
