Random Button

I seem to remember there being a “random post” button on sharenator.
If that’s just in my head, having one would be great because it would allow a wider variety of posts to be bumped by comments or upratings, instead of just things someone’s seen on suggestions, like all soccer videos, or demotivational posters.

On the other hand, if there IS one and my memory DOESN’T fail me, could someone direct me to it?
