@marathon Thanks for advice. Indeed, slowly I am discovering the emergent dynamics of this space. I am patient.
One thing I noticed is that crawling the social graph is interesting. Apparently going to places, following people, engaging and then disengaging is a random walk, but slowly I am sifting through the crap and I already discovered couple of interesting and thoughtful people. In the end, no wonder - even odd people know normal people who in turn know smart folks. It just takes a while to discover them. I am looking at what they do and learn quickly. Still interesting.
Let's see. The experiment continues...
