"There are no bad questions if they have great answers"
When your searching for clues and information via a web search, you may search as badly as a questions was asked, you may search just like a bad title reads.
Having a great answer under any question, that would be found using a search engine, however badly one searches, can still end in reading great information, based on very well written answers.
Should bad questions be closed, probably.
Should great answers be deleted , probably not, especially when people take their time and effort to create good content, to only have it destroyed by others.
In the debate sense to Fixers answer bad searches, looking for good info, will bring up SU bad questions, if they still have good answers (not just accepted) the knowledge base is still available. If they are tossed, or rightly if anything is tossed , where then is the knowledge?
I take the other side of this debate, but still maintain/agree that indeed there is both questions and answers that do not deserve life. So as always make good judgment calls, as there is no ONE way, there is people making decisions.
