What is the leading theory on Summerhall? I was reading that part of TWOIAF last night and am now fascinated even more by it, but not sure where to read/discuss, and I don't really want to start the umpteenth "ZOMG Summerhall theory!" thread.

on the ASOIAF subreddit, I came across the Bolt-On theory. Is that discussed on here somewhere? It's ludicrous and yet makes a fair amount of sense at the same time.
