If I come across a question that I have what I think/hope is a useful answer but not necessarily a life hack, should I post it?
I'm asking because I came across this question, and posted what I thought was a useful answer that was down voted almost instantly. I do admit that it was more of a common knowledge solution than a hack. The reason I thought it was OK was because I had seen this answer which also seemed to be a common knowledge solution.
Should I delete that answer? Is it off topic? I'm new and just looking for a little feedback on what to do.
Update: Question Part 2 ... should I have left it as a comment instead of an answer? since it's relevant but not a hack?
Update 2: Here's another question with a well received common knowledge solution.
