Daniel R. Tobias You and Brandt both like to call Wikipedia an "attractive nuisance", but that phrase has a precise legal meaning, ...
Correct. Just like "Troll" has a precise D&D meaning:
http://en.wikipedia.org/wiki/Troll_(Dungeons_&_Dragons) "The average troll stands nine feet high and weighs roughly 500 pounds, ..."
However, the word has broader, metaphorical, usages in English.
The phrase "attractive nuisance" is used colloquially to denote a poorly-designed and dangerous creation, with the implication that the creator or maintainer bears some moral responsibility for the inevitable damage due to its existence.

I do reference the legal doctrine, in order to convey to people the legal concept of "duty of care", as the predominant Net moral ethos sometimes seems to support handing a machine-gun to a little child and saying everyone should be wearing bullet-proof vests anyway.
It would take a pretty adventurous judge to stretch the doctrine that far.
I think of it as a doctrine which helps to establish a general reasonableness of critic's views. Maybe I should refine it. But sadly, there just don't seem to be good forums for that sort of discussion anymore (or at least, I don't know of them).
