Probably the greatest benefit of open source software is the liberty it creates to unleash innovation and the unexpected. By giving everyone four key liberties - to use the software for any purpose, to study it, to modify it and to pass it to others - software under OSI-approved licenses can be used in any way to create anything. The last twelve years since OSI was founded have seen an explosion of creativity both in the creation of software and in its use to make wonderful things happen.
