I think you hit the nail on the head there.

This is also what makes "social networks" so frustrating to technical people: it's not about your idea or even its execution. Rather, it's about how many other apes you've groomed in the past, to the point they'll back you up ("retweet") no matter how stupid your argument or insipid your tweet. The politics of it, tribalism.

A 140 character limit doesn't help of course :-) but the need for soundbites, a shared communication channel for quickly correcting/reinforcing our perception of reality, goes much deeper than that. Twitter is just a medium.

Where it gets interesting is when you consider why human group-think and "shared" perception of reality has been so successful, in evolutionary terms. Why are apes not simply rational animals, instead of spending so much energy forever climbing social ladders and adoring celebrities? Why these complex super-human social hierarchies (religions included), what makes them so efficient?

Well...yes to what you're saying. But there aren't neat lines between our professional technical lives and our personal ones, in particular because we spend a lot of time hanging out with people who share our interests.

Social media is designed for friends, not technical discussion, it's just that human relationships of all kinds are messy and there are no clear lines. So one bleeds over into the other, this can be expected. I don't think that's social media's fault or the people, just a predictable consequence of "how the people be"
