Thinking about mashups this morning, I had an idea for one that I don’t think has been done yet.
It would be a three-way mashup of Google Maps, job listings, AND information from local mass transit so that you could pinpoint all jobs in your area that are accessible by public transportation.
In other words, it would help you find a job that you didn’t have to drive to.
Perhaps this has already been done — I need to get to work, or I’d look right now. But if it hasn’t, then you read it here first!
