I have noticed that* things that we have questioned about the show on the threads have been answered in later shows. Here are some of the ones I can think of

1) We were curious about Jacks tattoos and then Kate asked Jack about his tattoos
2) We were wondering how anyone could survive that crash and then Sayid questioned how they survived that crash
3) We were trying to figure out if Sun and Jin were Korean or Chinese, Michael let us know they were Korean
4) We were baffled as to why no one has lost weight especially Hurley, then Charlie asked Hurley why he hasn't lost weight

Is ABC reading our threads and answering our questions for us on later shows?

Those episodes were already written and being shot (if not shot already) when fans posted those things.

You have to understand, there's no question you guys ask that we haven't already asked ourselves.

Thank you, that makes sense.
