Review my project, Factolex - the fact lexicon
gojomo: This is somewhat like an idea I've been considering. So I think it's a great concept... and have strong opinions on possible directions.If your primary model is a ranked listing of 'facts' by a major 'term' key, it will be hard to outperform Wikipedia (or even Mahalo). When those sites' single-topic articles/pages are well-written, they already lead with the core facts, and then proceed through the rest in a well-organized fashion. Even the Google 'snippets' in natural search hits then turn out to be pretty strong for anwering people's questions/queries. So I think to differentiate you need to break out of that linear model somehow.The multiple licenses situation is confusing and may prevent you getting proper credit for openness.You may hope voting and reputation will be mechanisms for gradual quality improvements, but they often backfire. Any benefit from people seeking to 'climb' for the right reasons can be offset by gaming.It's unavoidable you'd need to use some bulk automated processes (like scraping Wikipedia or hired contributors) to bootstrap, but that may then undermine the organic growth of 'community spirit' and norms that will be essential for the long term. The right balance will be hard to find.Good luck!
