I think a great way to spread the ideals of free software would be to make them more available to the end-users. A great way to do this would be to add options for GNU/Linux distributions under the operating systems tab. I believe a great way to do this would be to add the different distributions, such as Debian, Fedora, Gentoo, linking them to their respective websites (perhaps even hosting the latest iso on here), then giving a list of websites which sell pre-burned CDs or even a donation link.
As of right now, there are no options for operating systems other than Windows on here, and that is an ethical issue.
Perhaps to even go further, add in other operating systems, such as *BSD, Plan9, Android, etc.
Then to go even further, add in support for hardware with GNU/Linux. Maybe adding which have free drivers and which only have non-free drivers. (that can be found at h-node.org). That would be great to have for me, as I really enjoy using this websites; the only down-side is having to scour the Internet to find out which hardware would be supported in Debian GNU/Linux.
