Geeks get excited by the same things.
Bitcoin encapsulates most of those things… programming, the internet’s “anything goes” mentality, open source, computer hardware, and a community filled with other geeks… Add an affinity for disruption, and few of us can escape Bitcoin’s pull. When geeks have their first encounter with the topic, the phenomenon usually induces giddiness and profound question forming.
Geeks have so much to internalize and mull over that deep questions are asked of the community (ranging from technical inquiries to endgame extrapolations and conspiracy theories). When geek-celebrities are drawn into orbit, their fascination manifests itself in their audiences’ imagination–the ultimate halo effect. I have Steve Gibson to thank, while others (like Robert Scoble) have @Jason.
