CommuterEdge is the latest launch. It is a site dedicated to discussing the various hints, tips, and tricks for the modern commuter. The tricks could be anything from uploading documents to your Kindle so you always have a copy with you and extended battery life required for a long trip, to paths in New York to take so you don’t get run over while riding your bike to work.
The site just moved and has an empty database, so go help populate it by visiting CommuterEdge.
