u know what, gentlemen? It'd be really good if yall started acting
like what I just called u. Not every1's going to agree w/everything
others say. But calling folks ignorant, etc., just isn't right. U can
disagree w/a person's statements w/o attacking them as people.
Cultivate that skill w/programming & this list will be a lot better
place to hang out on. How do yall think prospective newbies to this
list are gonna react reading this thread when there's name-calling &
such going on? Not too positively, I don't think.
Lastly, I'd say that while having the requisite programming skills is
important, so is being able to interact well w/others. No1 talks about
that much, but it is a skill employers value. There's no reason why
these subjects can't be discussed w/o throwing personal attacks into
the mix.
