So many times, a simple question is given a 'correct' answer (I shall use one of my own 'answers' as an example - Upgrade iPhone 5 from iOS 7.0.4 to iOS 7.1.2)
The chances are that this is the 'correct' answer, yet the OP will never return to show it as such (it doesn't matter for this case whether my actual answer was right or not, it's just an example) & so this question will hang in perpetuity, hogging valuable Google space if nothing else.
The question already has a few up-votes, so the regular 'bad question' scenario doesn't apply.
I guess my real question would be "Does this type of non-question/non-answer" quickly drop off SE after some time, or does it really hang around forever?"
.. or "Can this stuff be cleared up manually?"
