Prevent upvoting questions at +10 on Area 51
I see a lot of people making comments about how voting for an example question that has already achieved 10 votes is a waste of their vote. This seems obvious, but people still do it en mass. Is there any practical purpose for even letting it happen? Why not cap the voting at 10 so we don't have to watch in agony as vote after precious vote is thrown away? Perhaps use a pop-up box over the button when someone tries explaining briefly why they can't/shouldn't do it, so that more and more people become educated in how this whole system works?
Edit: Or as an alternative (proposed by @SF.) just have the popup warning?
Edit (2/2/13): It has been pointed out that there is a similar question here and that this may be a duplicate of that one. However I would like to mention that this is not a complete duplicate because because I also suggested the pop-up feature. If that is a valid enough question on its own I can always propose it as a separate question and close this one. A good enough point has been made to not impose a physical cap, but I still see tons of people making posts about how everyone is throwing away their votes on a question that is already +10, so perhaps the community should be made more directly aware of the system to reduce or prevent the noise and drama created by people constantly posting that. It has also been stated that SE has survived without such a feature, but what kind of community would we be if we didn't actively seek out ways to improve things, even if those proposed improvements end up being deemed unnecessary?
