Network based economy = Tribes?

Seth Godin's best seller talks about organising ourselves into "tribes". And this is indeed something we naturally do lately. We live in a network based economy, not to be confused with clientelism. It's just functional.
Large service provider institutions often let us down. So we look for solutions outside the "prescribed pathway" - through talking to people who know people who may have an answer to our question.
I find this great and would like to encourage others to do this: look around to see who is in your network and see what value added can you bring to them and vice versa. Networks are also open, thus the different networks one belongs to can become interconnected through one of their members. Over time more and more overlap will be discovered and more networks will be connected into each other. Organically, naturally, elegantly.
This may be something YOU have always been aware of and built on, but I am just in the process of discovering how it works. I feel I always had the opportunity to connect people who had common needs or interests, but never really looked at it from a systemic perspective.
And now I do.
It is beautiful. It reminds me of Garrett Lisi's Beautiful theory of everything on TED. And of Margaret Wheatley. Everything seems to be falling in its place in a seeming chaos.
