I was wondering, of course only if Zach would agree, if it wouldn't be better to have the oldest episodes on the bottom of the 'episodes to follow' list and the newly submitted ones on the top? It would definitely give the new branches a better chance to be added to and distribute episodes more evenly in the episode tree.
From what I know about webpages programming that change shouldn't involve more than just re-writing a line of code or two.
Also, does anyone else think it would be a good idea to have an episode's rating displayed next to the link leading to it?
