I've been reasonably active on biostar for ~5months and overall the experience has been great. But, one minor disappointment is how few votes people tend to give out. There are tons of good questions and answers with just 1 vote. It seems some very small number of dedicated moderator types are probably checking out most questions/answers and giving a vote if they like the post. But, run-of-the-mill users are not voting much? One way to encourage more voting could be some additional badges. Currently there is only a silver badge (Civic Duty) for voting a whopping 300 times. By the time a user gets to 300 votes they've probably stopped paying any attention to badges. But, when users are in the honeymoon phase, and still gleefully trying to earn badges, perhaps a bronze badge for 50 votes, then silver for 100 and gold for 300 (or some similar scheme) would encourage the voting habit?
I"ll look into this, we could add more badges - but also perhaps we could add a small reminder feature: if someone has not voted for X period of time (say three days) a reminder message will pop up every once in a while. I don't want to make the system too clingy, but a reminder here and there might work well.
I like this idea of periodic voting reminders.
