So what did we learn from the Lost internet thingy this summer?

With Lost starting back up tonight, I’m sure there will be occasional references to the online experience game thingy they ran this summer. I wasn’t interested enough to spend the time with it, so is there a summary out there somewhere of the whole thing so that I can feel up to speed before the fun begins again?

Full summary of everything revealed by The Lost Experience.

May contain spoilers for the series but may also contain information that won’t be revealed there, so decide on your own if you want to look or not.
