Reading this post I get a nice feeling of joy for belonging to the software community.

Being so entrenched in the software world it becomes easy to gloss over these details. The outside perspective of this article really shines a light on how well the software community collaborates and shares.

I can't think of a single community that even comes close to the level of collaboration we have in software.

Honestly, I had the opposite response. I think the claim that Github is the most important social network is willfully ignorant of the role Facebook/Twitter plays in every industry beyond software development -- or, more accurately, the role Github doesn't play.

I agree. One of my good friends is a realtor. Facebook changed the way she does business. It is the source of 80+ percent of her leads and is, quite frankly, the MOST important social network to her.

Github may be the most important social network for a certain class of open source developer, but the author's attempt to extend its importance to demographics beyond this group makes the author sounds as if they're just trying to stake a claim as an early member of a new "cool" social network.
