Can Web 2.0 Grow a Web 1.0 site?

My business partner, Dean, and I are trying to develop a web 2.0 marketing campaign that’ll help drive relevant traffic to our foreclosures website.   The site ranks well under some key terms, but we need a campaign to drive additional traffic and new links to further improve the rankings.

The site is made up of simple foreclosure listings gathered from a variety of sources.   It’s free and totally searchable by site visitors.   So, the question is how do you develop a web 2.0 marketing campaign around this very web 1.0 site?

Two thoughts dominate our thinking:

Video with user/viewer feedback
and
Creating compelling content that’ll help us generate new links to our site

Since the site is fundamentally about finding great foreclosed homes either to live in or as investments, we think we could create content around choosing the best property.   Here’s how it would work (roughly):

We’d create a weekly video series where we feature two different foreclosed homes listed on FreeForeclosureDatabase.com.   In the video, we’d run down the stats on the two homes then invite people to vote on which home would be the “better investment”.   They would be directed to vote by going to the foreclosure website.

I’m thinking we’d have a contest for those who vote… Maybe a random drawing or something like that to encourage people to vote and create a way (and rationale) for collecting an opt-in list.

Of course, there are a lot of additional details to all of this, but this is the core of the idea.

Have you seen any other successful web 2.0 marketing campaigns?  If so which ones?
