Quoted from robin:While my intentions for the follow feature have nothing to do with popularity, I do see what you mean. Having a little status icon under your name listing "only" 1 follower may be kind of disheartening. Again, following should not be a status thing but I do realise that's how some will interpret it.
As a new pinsider, I see it more as a reputation thing than a popularity thing. Easier to trust the advice of someone telling you how to wash circuit boards etc. if a bunch of others are following that person.
