I've seen a good bit of Linux specific talk, but i haven't seen to much Linux elitism here (although i spend a lot of time in Linux specific communities so maybe I'm desensitized). I'm just glad the board isn't over run with distro wars over who's pet distro is better for Bitcoin and network security that another's pet distro.
As for the the rest, I think its just the uncertainty in the air lately that none of us want to admit to. With the hacks, malware, scams, and rampant trolls plaguing our beautiful baby currency, it can make one feel a little on edge about investments made, and we take out on each other.
Hopefully as each of these issues are resolved/diminished we will see a return to a more friendly atmosphere.
