Da Massive writes "The number of open-source projects that use the GNU General Public License Version 3 has grown to more than 2,000, according to Palamida, which sells software and services for tracking open-source code within a customer's code base. 'Our database now contains over 2,000 projects that are using the GPL v3. "At this rate the GPL v3 is being adopted by 1,000 projects every 4-5 months, and if the trend continues, the license will be used by 5,000 projects by the end of the year," states a recent posting on Palamida's blog.'"
