You go to the season post to get an overview and general feel for the season, plus any and all questions or fan theories are welcome.
Individual pages so you can talk in depth about an episode or post questions as you watch, with spoiler free answers.
I wouldn't do the four discussion threads, but that's just me trying to cut out redundancy. If others like breaking it up, hell, I'll give it a try. But i mostly watch Star Trek with the wiki and/or Reddit page up so i can look up trivia and actors i recognize, so one post per episode and a megathread for the season are right up my ally.
