Tool & Story Ratings
User ratings/votes as a feedback mechanism for tools & stories.

Background
Currently, tools & stories are always shown in order of most-recently-created, both on the home page and the Tools & Stories page. However, the most recently added tools and stories are not necessarily the most useful.
The only way to offer feedback on a tool or story at the moment is to add a comment. There is no way to summarise this qualitative feedback, however, and therefore no way to find the tools or stories that they community collectively finds most useful.
What is the essence of this suggestion/idea?
Add a rating or voting system to tools (and stories) that allows members of the community to give quantitative feedback.
What are the potential benefits of this suggestion/idea?
Encourage feedback loops and help give the community's best-regarded tools and stories more visibility.
Who would benefit from this suggestion/idea?
Community members looking for high quality or community-recommended tools and stories.
