I've seen several cases where the asker has simply put 'I don't know what to do' or 'help me' with no individual effort and in some cases it is clear this is a homework question (i.e picture etc) and these questions get more views and comments from people trying to coax a solution out of the asker and provide lot of hints to help he/she to answer the question. Admittedly these questions get more downvotes but that makes them stand out more and people visit the question to see why the question is so unpopular. This gives the asker an opportunity to show some working and get his question asked promptly.
Whereas if someone asks a genuine question with sufficient working to show effort it does not garner the same amount of attention per say. And often these questions are not answered as quickly as some of the worse questions on this site. I know there is nothing we can really do to combat this as people answer whichever question they like, but its just one of the small things that annoy me that I thought I'd share.
