I'm building my own Q&A community based on open source software that is governed by the GNU General Public License. So far I have been outsourcing the development to different programmers, but it is getting to the stage where I feel it would be wise to have work-for-hire contracts in place in order to protect ownership of future changes/features on the site. The GPL, however, requires that any modifications made to the original source are made freely available for distribution along with the source code.
I understand that Digg, for example, was originally based on open source software, so I was wondering if this step of IP protection is something that should wait until the business has scaled, at which point the code could potentially be rewritten from scratch?
