Listiki lets you find, make and share lists of stuff you care about. Listiki, at heart, is a deceptively simple concept: collaborative, live, ordered lists that can be generated by anyone. Listiki will harness the power of the real-time web via Twitter & other social networks to add a layer of context and hierarchy to this massive, constant flow of data. It's a tool that delivers order and relevance for any topic.

Demolistic is a list-building community. Create, edit, share, and discuss ranked lists. If you disagree about the rankings on a list, you can create your own version of that list, and the system will generate a "master" list with the average ranks of everyone's list on that topic. It's basically a ranked choice voting system for voting on anything.
