just rehash of some popular myth

You'll have to show me examples where myths persist unchallenged. I don't believe this one for a second.

maybe copy-paste of perldoc perlfaq

And why should it not? First of all, why waste time writing an answer that is already answered? Secondly, maybe the seeker was not aware of the existing Perl documentation; assuming the poster mentioned where he got this copy-pasted answer from, it would help the seeker learn how to (attempt to) answer his next questions for himself.

those elaborate and extremely popular answers usually have nothing to do with question at hand

Looking at my own top 100 nodes and those of others paints the opposite picture.

Sometimes it looks like they were created by some simple bot

Short answers? Maybe. Elaborate ones? You'll have to show me. I never got the feeling around here, ever.

And all that aside, you seem to expect of the voting system different things than it is able to accomplish. I wrote about what I think it does according to observations (rather than expectations) before.

Hopefully my quoting you and addressing points directly will hold as sufficient proof that I actually read your node instead of running a bot that responded to it. And maybe that justifies the fact that I downvoted you for wildly exaggerated unsubstantiated claims presented as fact.

Makeshifts last the longest.
