Here it's probably relevant to place myself into context:
I am really new to Debian so at this stage consider myself more of 'the public'.
My reason for involvement is that I am interested in combining hacking and biology, in the DIYBio, BioPunk sort of vibe, and I also ran TEDxCapeTown from 2011-2013 (not this year). So I think I can add value in the eventy type stuff, I'm based at UCT doing my PhD in Bioprocesss Engineering ( which equals flexible time availability and knowledge of how universities does stuff), but when I say stupid things like 'get Microsoft to sponsor DebConf', then please be gentle with your criticism - but still teach me :)
I am really passionate about getting the public more into science, hacking etc.
In TEDx we tried something called the XLab, where we had people display their stuff in ways the public could interact with it. I suggest we do something similar just before the conference, so that interested people can attend. In addition we could put a 'P' next to talks or whatever that we consider public friendly.
My suggestions for this sort of exhibition would include: (None of these have been contacted yet, but I have worked with some of them before) (also, must this go on wiki or in an email thread?)
