We've had some confusion in the past about our site scope, but we now have a clear description all in one place, with community consensus (+7/-0 is pretty substantial for our meta). So, what should we do about questions that don't meet these guidelines (and can't be edited to fix that)? Should we attempt to review extant questions for scope and close where needed, or should we leave things alone until they naturally pop to the front page and deal with them then?
Having open questions that violate our current guidelines can confuse people ("why was my question closed if this similar question is ok?"). Reviewing all the questions would require a substantial effort from the community. There may be a middle ground.
