Yep, totally. I got "Is reddit down?" from over a year ago, with 14 points, linking just to reddit.com. Clearly not a top post. Default the points to >=50 at least, possibly with an option for users to set it.
Great idea though.
And also a way to may be down vote/eliminate certain posts.
Eg:What's new in PostgreSQL 9.0 - a User's Perspective,382 days ago. Wont be much useful.
