i think it's friendly if ideas gets discussed with respect to others and on proper timing when we all had free time...

on the contrary, we may all find a foe if official working time is used up in QL discussions... for One, a big FOE coming from our bosses :(

personally, we all get to benefit in one way or another by means of time spent bringing forth ideas and fun altogether.... that seems "friendly" enough generally, at least on my understanding...
