Build a Website

We're looking to create a news website where users share favourite articles from other news websites. The links will then be voted on by other readers/users and top 10 lists will be generated based off the voting. We want this website to be very simple (and cheap) with a Web 2.0 design. The website won't actually be used to publish articles, just to share links. What we want users to be able to do is: - Create a personal account - Share links specific to predetermined categories such as International, National, Technology, etc. - Vote for or against articles - Comment on posted links to articles We want the site to be nice and simple so that anyone can navigate around it without any trouble. We also want users to be able to collect points for the most visited link. For example, for every link other people click on that a user posts, they get points. The tally should be visible in the users account information and top users should be on a scoreboard.
