Elgg, an open source social networking platform, opened its development process much wider the past few months. Not every company that goes fully open source benefits from the changes in their license or the changes in how they develop and manage the code. However, open source seems to be treating Elgg very nicely these days.
Since fully opening up Elgg development and having a core team of developers working on it progress has been staggering already in terms of fixes and enhancements, but also in community discussion. Eric S. Raymond's "given enough eyeballs, all bugs are shallow" certainly holds true in the case of Elgg, because what may be of most interest is that security issues are being discovered one by one which have been in the code for several releases already.
