I've been there for just over a year.  My reactions are basically the same as his - they <i>were</i> the same when I started, but they've dulled as I got accustomed to it.  Still think it's a great place to work.<p>The OMG-everyone's-so-smart factor does fade as you get accustomed to all the proprietary infrastructure and realize that hey, I'm smart too.  Eventually, intelligence just doesn't matter all that much.  It's like my dad's story about starting at MIT: the first 2 weeks, everybody has their phi-beta-kappa rings on all the time.  After a month, they've all disappeared, because you realize that everybody else has one too, and then smarts just aren't an issue afterwards.<p>You also tend to become more overworked as you gain competence.  There's far more that we'd like to do than what we can do.  Eventually that marveling at "Oh my god we built this" becomes "Oh shit I have to build this", which can be very satisfying, but also is a lot of work.
