The Tux Project
There is a project in its infancy which aims to gather people from the community with ideas on how to promote GNU/Linux. It comes out of a post-Tux500 discussion on what to do next (after Tux500) and some (me included) thought a good idea would be to set up a central organization / website which would gather promotion ideas and help organize them. That project is now The Tux Project.
I have joined, for now mostly as an observer (since I don't have any big ideas right now) and in reading I encountered one thread which presents an idea of a site much like GetGNULinux.org: http://thetuxproject.com/node/68
I have commented to tell them about GGL. Another guy also suggested gnulinuxclub.org. I am just informing you that this project is there if you'd want to get involved, get in touch, discuss (with regard to that specific thread) the differences and different directions of various ideas for a site introducing people to GNU/Linux etc. I thought you might be interested.
