Jason responded that his philosophy is "balance." That's all well and good, but is that consistent with his involvement in Groupon? That's how this originally came up.
Certainly he has been very gracious to respond at all, and I think he's convinced me (and hopefully others) that there is no necessary inconsistency in preferring balance for one's own company and rapid growth for another -- or simply acknowledging that even if one doesn't gel with another philosophy on rapid growth that one can still provide valuable advice on design, etc.
Is that consistent with his philosophy as stated in Rework? I'm still not sure...
And I have a thing about us accidentally chasing primary actors in the tech community off of HN by acting like... you know... us.
so it fits his filosphy well - seems like he wants to get out of it slowly and profitably ..
If you're interested in how 37signals is operated, you should start a separate thread about 37signals.
Groupon and 37signals are very interesting contrasting Chicago tech companies and would make an excellent comparative study, but Fried's involvement with both companies doesn't really set up the "consistency" narrative you're (maybe inadvertently) creating.
