(I've visited and been a resident ... I guess I'm one of the non-high-profile ones). From my N=1 anecdotes during several visits, the vast majority of attendees were not "high profile" (whatever that definition is) ... and most people spent most time heads-down doing work or pairing/in-meetings talking about work. from what i observed, there was very little showboating. it's not like a 3-month TED conference or something :)
