here's an idea that you can build and then pay me lots of money for:
A site that fixes the commuting problem, at least for some jobs. No, not teleworking. Consider this scenario:
Let's say you are a web developer, living in city Z, and every day you spend 2 hours commuting to your web development job in city X. Unbeknownst to you, there's a web developer living in city X, who commutes 2 hours to her web development job in city Z. So my idea would be to connect these two, and see if their bosses agree to a web developer swap. Boom, 2 commuters less in the world. Granted, that's a huge "if", and this system won't work for all jobs. But might be something worth exploring.
The one issue I see with this is that there are too many variables outside commute that make these employees not very swappable (i.e. cultural fit, skillset, etc.).
It's hard enough when it's just one employer and employee involved. Now add another set? If any of the four parties involved aren't good to go... then it won't work.
I could be wrong, but just seems a working scenario is too rare to justify this as a variable business/network.
