This is a follow-up to What can be done to improve Physics.SE as an active forum for physics researchers and student's?.
Although I disagree with the motivation behind that question it does seem to me that there are a lot of frivolous and lazy questions at the moment. By this I mean questions that are either copied and pasted from homework texts, that would be answered by a quick Google or that would score high on John Baez's index.
Site members can already vote to close a question, but we can't vote to delete (though we can flag for moderator attention). I wonder if we should have a facility to vote to delete in the way we can vote to close.
