Recently, we've seen some highly upvoted questions on PMSE. This is awesome! I give credit to MattiSG's comment on the "What is a 'battery'?" postMattiSG's comment on the "What is a 'battery'?" post.
@CaffGeek If you're curious too, then perhaps could you consider upvoting the question? :) This is absolutely not greed, but simply giving more chances to the question to be in the “top questions”, get more views and more possible answers.
These types of constructive comments are exactly the types of comments we should leave to remind people visiting the question to upvote great, useful content!
As an aside, we shouldn't forget that downvoting is an option as well, and those votes should be used on questions that don't show research effort and on answers that are either wrong or don't answer the question.
Also, MattiSG makes a great point! Our top voted questions page is a little iffy, IMHO, as there are quite a few not constructive or list-style questions that we haven't yet got around to cleaning up yet. One way to push these questions down is to upvote other great questions that we want to see on the top page! Great suggestion, and great comment!
