Well, I think its an idea. I don't know too much about it because its not explained very well. You might want to look at how other web 2.0 companies are mixing selling and explaining on their homepages, because they do it really well. You want to make people want to start using it, but also explain what it is very quickly. there are some great websites out there that make great use of the available space and use color really well. So part of the problem is you need to work on that.

Even the stuff you just said in the comment above can be used to promote your app, you've just got to use it. "Want to save gas?" "Think more people should drive together?" "With Private Transit you can do both." "Just map out your route and see if it matches up with others. Organize a pool and you're on your way to saving money and the world. Your co-riders can chip in with cash or pay their share using PayPal through the website." "You can even keep track of miles, print out reports or get email updates to your mobile phone if someone can't make it."

I mention all this is that no matter how good the back-end coding might be, if people don't understand it or are encouraged to use it, it won't take off. Coding was the tough part, but now design and marketing is the next tough part. It really needs to be almost as important as all the work that you've put in already.
