A 'voting' field for lists

It would be useful if a list could be turned into a tool that people could use to gather votes on the items within the list.

For example, if you made a list of all Morgan Freeman movies then you could let people vote on their favourites. Of course, there are already sites where you can vote on your favourite movies, like Metacritic or IMDb! But there are millions of niche topics that are not popular enough for a site like that to be built, and Listium could be the tool that people use to gather votes on thousands of niche topics. It could also be used inside private Facebook groups and places like that, where they are only interested in the votes from members of their community.
