on a side note, whenever i asked such open ended question on stackoverflow, it would quickly get closed by some other user claiming that "there is no right answer" and the question must be closed. But there are so many great open ended questions on there that score so high among users. i guess it's a matter of luck that some anal retentive person doesn't get to it first?
It's not exactly luck. Until today this question hasn't been active since 2009, when opened-ended questions were permitted. Now that it's been bumped it'll be closed shortly.
