Voting for user lists

Hello team, i would like to propose an option to vote for user lists. Then they can enter a contest. and Top 250 most complete/interesting lists of movies. For example:

1. user visits my list and he likes it - he clicks "vote for this list"  (similar to FB likes)
2. lists gathers a lot of votes and goes to top 250 user lists

Also it will be useful for the user, who created the list to be able to receive recommendations from users with titles to add to this list.

Thanks!
