What would you do with 750,000 users?

My friend Darren Herman has issued a very interesting challenge on his website. The challenge to entrepreneurs is to solve this problem:

I’d like to pose a challenge to all entrepreneurs or established companies who are looking to increase their distribution (and business) in the digital media world.  I’m friendly advising someone/company that has legal access to over 750,000 US Internet users and we are trying to come up with new ways to monetize the audience.

Distribution will come from access to a ‘portal’ like page and thru email announcements.  How can we monetize these better and/or release a new product/service/solution to this audience.

So, do you have an idea for what you would do with 750,000 users? Fill out this form and you could win!

Good luck!
