This is the idea;

-any registered user can post content to the site
-Each content item comes with a poll that is displayed to members and/or guests. The poll asks wether the article is Advanced/Mediocre/Beginner in terms of the level of quality of the writing.
-The different levels of content items correspond to a drupal feature that allows them to be sorted. I was hoping this could somehow be done with the taxonomy module, eg if an article has 70% of it's votes for Advanced, it will be associated with the "advanced" vocabulary.

Is this somehow achievable with existing modules?
