Normally the logical process when seeing a question is:

1. Is understandable -> edit, vote, comment, close
1. It belongs here -> vote to close
1. It have been already asked -> look for a dupe
1. You know the answer? -> write an answer

in which each step has an exit behavior. Now, there are several users on internet, each one with their own methodology, so the above is not always followed or there are cases where it's not applicable.

I believe all easy questions already has answers, and answerers needs to be prepared if a moderator comes around and delete their answer because it breaks redirection.
