Yeah, building a population of contributors is hard, as I'm discovering ( http://payload42.com ). There might be some decent suggestions at http://meta.stackexchange.com where folks are trying to figure out better ways to seed Q&A sites.

I noticed it, but am too lazy to create one. Love the site though it took restraint to not keep going, there's some great match ups.

Also, it would be cool if it showed which film is winning out of a given pair after you vote, like hotornot shows you a person's score after you vote on them.

You could always have a counter or something that will trigger a popup (or new page) that hightens the awareness of making your own match-up. If this is a goal for this website, it is definitely something to look into.

If there's a "make your own match-up" link on the page, I didn't notice it. Granted, I wasn't looking for it, but there you go.
