HackingHealth.ca might be of interest to some of you who want to help but not necessarly know where to start and/or find the barrier of entry very abrupt. It's an event very similar to a hackaton where developers, designers and health professionals work together during all the weekend on real practical ideas that will be tested in clinical environment shortly after. Two have happened in Montreal and Toronto and where huge success. The next one is in Vancouver, late February. Lots of other cities are coming in the following months (sf, melbourne, london). Anyhow, feel free to email me (phzbox at gmail) if you're interested in sponsoring or organizing one in your city; I'd be more than happy to help a fellow HNer wanting to hack health.
