For some stuff I don't care, some other makes me jealous and some other is actually cool to discover/learn (think of some new place to have lunch/dinner or some hobby you didn't know about your friend).

But in general I am with you, and I also feel like most people liking and commenting are playing the social game.

I am not very active in social networks, though...

The comeback of crack and medicines!

As a tech enthusiast and software developer I think this is amazing! I would love to have them in my hometown in Spain :)
