Newbies often forget that they should pick a best-answer(or even upvote). May we remind them? i.e, for someone with under 100 reputation there could be a ribbon/pop-up that suggests they vote up, or choose the best answer.
Perhaps this should be triggered when an answer has at least 2 upvotes(to prevent having the system goad on a user to pick any ole' answer as best). The hope being that after gaining experience, they will be better able to decide the 'best answer' question.
I realize the system does this in the very beginning, but perhaps this can help some more.
We should not need to goad on newbies with such simple requests(cf. with if it can be automated). And it's apparent that we like our SO points!
It's somewhat minor but would likely save some time for us(and help get newbies up-to-speed faster).
