It's "unrealistic" because there are social realities that exist outside of the valley and tech blogs. It's true that it's a good company, and it's true that it's a darling company here, but there will be sectors that haven't heard of these kinds of places.
And, again, once you hit something of size, some delineation is a necessity. You don't have to model the Marine Corps, but when you have 30 people arguing over something, the buck has to stop somewhere.
The buck always stops somewhere. Whether you're two people or three people. At 37signals, the buck stops with Jason and me. Now it happens to be that when you employ smart craftsmen and women who care about what they do, there's very few loose bucks to stop.
Employers that worry about this are rather silly. I'd hire a candidate even if he was starring in said porn productions.
Maybe it's just a scarcity mentality thing; they're worried about turning off potential employers, but when you're constantly getting contacted by recruiters I guess it's hard to feel like it's a disadvantage.
But give them an opportunity to serve as team lead on a successful project or several, and you've got plenty of resume mojo to spread around to everyone.
Also, more pragmatically, how realistic is it to have 30 direct reports?
