Indeed!
That's why I always answer 100% of my comments... The truth is interaction is key on here, this is a small tribe when you consider other content platforms, and people above 60 in rep mostly know everyone else above 60 as well.
So friendships, communities and interaction play a larger role here, on this "small village"
I know only a few above 60 :)
There is no problem with having friendship circles, as long as we try to keep expanding them!
