Mods, is there a rhyme or reason behind question deletion?
I've been on long enough to recognize "questionable" questions and therefore will wait a good period of time before answering or commenting on them to ensure they are not deleted. But now I'm seeing questions that are HOURS old that I spend a great deal of time typing detailed, in depth answers for, only to see the question later deleted. I'm becoming reluctant to wasting my time trying to answer many questions without understanding just what triggers a deletion.
Any guidance would be appreciated. Thank you.
