Can someone explain how this differs from Erlang? It is briefly mentioned on the Go site:

"One of the most successful models for providing high-level linguistic support for concurrency comes from Hoare's Communicating Sequential Processes, or CSP. Occam and Erlang are two well known languages that stem from CSP. Go's concurrency primitives derive from a different part of the family tree whose main contribution is the powerful notion of channels as first class objects."

I am not sure if this is an option for you, but the bike commute can be a great way to exercise, with zero additional demand on time. I recently replaced my car commute with a bike & bus combo. I work in Bellevue and live in Seattle and the buses have bike racks. I bike the Seattle section to lake Washington, take the bus across the bridge and then bike to work. It takes about 45 minutes including waiting for the bus door to door. The car typically took 45 also because of long wait times for the bridge. The buses alone were worse: about an hour. If the 1.5 hour commute can't totally translate to the bike, it may well partially translate like mine: bike and bus, or start in the car and ride once you are closer.
