Crowdsourcing Health Research
Although the post calls this "open source health research", it's more a matter of crowdsourcing, since it lacks many of the elements of open source - true collaboration (rather than massed effort), modular organisation (rather than loose collections of separate facts), etc. But it's interesting nonetheless:There are definitely a lot of patient communities based on stories and support. But there are very few patient websites based on data. CureTogether is a data-driven site, bringing people with different conditions together to compare symptoms and treatments in a quantitative way.
Indeed: putting that data together in a way that is useful to researchers is an important task, even if not truly collaborative in the open source sense.
