> I'm not totally against the people centric model. I think it can work well in social networks like Facebook and Instagram that are more friends and family focused [...]

I feel Instagram is 100% influencer focused -- i.e. sponsorship focused -- with just enough "friends and family" to not make it feel like an advertisement show.

You know how music on a commercial radio station is there to fill gaps between ads? That is Instagram and Facebook! Same concept but "done with computers". :)

Not judging, just expressing my disappointment about the lack of honest separation between ads and private life.
