Currently you have to query the DB via the command line to view responses from Special:MirahezeSurvey. This is a time consuming process when you are dealing with hundreds of responses.
We should create a special page (probably only accessible if you have the userrights (maybe view-survey-responses?)) that allows you to view survey responses or overview of user responses. Perhaps with charts or response percentages? This would be easier then having to scroll through hundreds of DB entries.
