Just below every MO question appears the following line set off in a box:
Remember to vote up questions/answers you find interesting or helpful (requires 15 reputation points)
My question: Should we too have something along these lines, to nudge people into voting up questions/answers that they like? I feel that we should: the reminder helps one remember translate one's appreciation into a vote.
I was prompted to ask this question by the rather low proportion of votes scored by even the most popular questions here. MO questions seem to score around twice as many votes for the same amount of popularity (~ views).
