My idea was to gather them in a new post. Numbering all of them. Everyone who votes gets 3 points to share over their favorites. (So either one story with 3 points, two with 2+1 or three with all 1 point). And then we add up all the points after two weeks or so.

I thought, if everyone just gets one vote then we might not get enough votes (or too uniform) to actually see a difference. Hence 3 per person. I had a system like this before and it worked quite well.
