Most notably for minecraft, but I'm sure this happens with others as well, many questions and answers become irrelevant after a certain amount of time or after a game update.
So should there be some mechanism, like a tag or some kind of flag, to signal to members and googlers that the answers for a certain question might be in fact wrong for the current time period? Or perhaps should mods/members take it upon themselves to edit answers/questions to reflect the time sensitive nature of the information contained therein?
On a side note, this is my first meta question and I was unsure about how to tag it. Retagging as necessary is welcome and appreciated!
