looking at the list again, I had the same feeling...despite that any statistician would slap us in making assumptions with such low numbers! But the trend with these users looks like more organic, I agree.

you can do that for sure...having a list of users with comments highly curated,just the details if there was specific curator(s) pushing the button wont be possible, unless there is a list somewhere :P
