Still not sure why the fascination with others. Nice work on the numbers here though not sure of the purpose. Actually it seems to indicate that members on Milepoint are happily adjusted to social sharing with others in a friendly environment and yet still are posting some very impressive content. Funny thing about your list. It would seem to indicate that there would be about 641,510 +/- posts of relative information (after deducting your list of social sharing) after 2 1/2 years on Milepoint. One might say that's pretty respectable since a quick comparison to FlyerTalk after 2 1/2 years according to the Internet Wayback Machine indicates FlyerTak had 282,315 +/- at the same point:

I'll leave the number crunching to you but I think it fair to say good for them with what seems like very positive success in whatever it is they are doing—it helps the average frequent flyer and there's really nothing wrong with that.

So, why don't we do this—quite worrying about any others and continue to work on building FlyerTalk for the better. One of the marks of great communities is they hold their heads high, wish other efforts well and always look forward to helping the next member with some information relative to their travel.
