Right now I plan to use #Ikiwiki or #mediawiki for the planned application/site resource, since that's what #freedombox comes with. So far I've been putting in the ideas in a blog post draft, but now I'm thinking of just first putting it in a personal wiki, and then exporting that to one of those wikis. I want to feature #howtos, #hacks, #links, and so on and so forth to make a full featured resource.
After looking at sites like #disroot, I would like to make a site like that.
