The O’Reilly Open Source Convention (OSCON) saw the announcement of a new open source advocacy group that seeks to encourage the use of open source software in government.  Anyone can read Open Source for America’s Charter here.  Coverage comes from O’Reilly, Ars Technica, and InformationWeek.  While reading one of the sources that covered the announcement, I found this site which notes that a Federal government database shows open source software has fewer vulnerabilities than the equivalent closed source software (think Windows, Microsoft Office, Oracle, and VMWare).
