I am suggesting a website where people who travel a long way to work and wish to find a similar job nearer to home could enter their details so they could begin the conversation about swapping jobs with someone who could benefit in a similar way. E.g. I live in the suburb Smithton and work as an accountant across town in Joneston. Someone else lives in Joneston and works as an accountant in Smithton.
It could reduce our personal travel times and traffic congestion. It's not always (or even usually) going to work out but if it helps a few then it could be worth it.
A government initiative perhaps?
