or why Richard has been the same age since the 1950’s. Who cares?

Considering that they've bothered to age (or un-age) Whitmore, Ben, Eloise, etc. AND the fact that Richard's lack of aging has been explicitly mentioned on the show (Sawyer if I recall correctly), I'm willing to be that isn't a "Eh, whatever" decission, there's clearly something behind that.

While this particular one (Ben's wound switching sides) appears to be a major mistake, most of what's said on that site is yet more, 'Why do they keep leaving things a mystery?!?!" whining from Lost fans. Ummmm, because if they answer all the questions, the show is over. Why don't you wait until the show is done before you start bitching about things that aren't answered yet. I personally watch the show BECAUSE there are unanswered mysteries. I may be missing something here, but I'm pretty sure that's the point of the show.
