I still hope Damon and Carlton just do some sort of brain dump via an interview or fan conference to answer a lot of the questions that don't need story behind them to be answered.
My guess, Damon and Carlton took a red eye flight the day before the finale aired to some third world country where they don't have televisions and no one's heard of Lost. Given the reaction of some fans, which I'm sure they could anticipate, this would have been a necessary to ensure their own safety
Seriously, I know they've declared radio silence, but I hope it ends after a few months like it has before, instead of being permanent. To be honest though, any answers they give after the fact and outside of the show itself I would probably find unsatisfying (though I am perfectly fine with the show and how it ended and the mysteries it left unanswered etc.) In any case, that would be awesome if they did like a two hour movie "Lost: The Hurley Years" with Ben, Hurley and maybe some new castaways or other people Hurley brought to the island.
