Ah, the two sided marketplace problem. Who is the limiting factor, and how can you persuade people with those characteristics to join your site?

Is the limiting factor drivers or riders?

Can you explain why you think this is a two sided marketplace problem?

In my case the subscribers of my site are the consumers. But I need a lot of subscribers to start with so that when they sign up, and start to consume, there is a potential match.
