I trying to be constructive here. I not throwing a words that
*something* is stinks just because i don't like the *thing*,
i providing arguments and explanations why i think its err.. crappy :)
Oh, and i didn't used this word before Vassili started. Well, if
people want to defend their position more aggressively, i answer in
same style. But this not means that my point is not constructive
however.
Please do not take my comments as personal attack or ranting, i just
trying to put arguments and discuss why some things i think having
flaws.

Can't parse your last phrase. Please elaborate.
