i live/work next door to the hacker house. the most worrisome part of this whole visit to me was when i asked them why they were here, their response was "to check in on your grassroots movement" and used the words "counter-culture" twice.
this being said, our overall conversation was not too out of the ordinary. they asked what my startup did, i gave them the pitch, and then we talked about advanced manufacturing and the future of the american economy for ~20min. none of them smiled though.
This reminds me of how the Occupy movement was handled by the authorities.
