I wouldn't say "ambiguous". I'll grant you "subjective". Does stackexchange forbid questions where there's an element of opinion, because the system's set up only for questions with "one right answer"? That seems awfully restrictive in the name of a system limitation. Especially as, as 4ad observed, the asker chooses an incorrect answer annoyingly often -- so the "best answer" isn't always actually the best. As such, it's advisable to at least flick through the other answers anyway, despite this rule.
