The most recent example, in my case, was:
http://stackoverflow.com/questions/10166086/good-examples-of...
"Can anybody recommend some [PHP] programs for me to look at, that promote best practises, but are simple enough for me to understand?"
"closed as not a real question; It's difficult to tell what is being asked here. [no it's not] This question is ambiguous [nope], vague [no], incomplete [er, no], overly broad [no], or rhetorical [still no] and cannot be reasonably answered in its current form [no again]. See the FAQ for guidance on how to improve it [mmm, passive-agression]."
... er, WTF guys? Given the minefield that is trying to write good PHP, it's a very good question. A couple of good answers had, I note, already been given, which puts the lie to the mods' reasoning -- but they killed it off anyway, even though it was showing promise? Really?
Reeks of power-tripping or jobsworthy moderation to me.
