While looking for the best application of a Democratic regime, people tend to look either at Athenian Democracy (as applied in Ancient Athens that is) or at Grassroots/Liquid Democracy (as supposedly promoted by (some?) Pirate Parties worldwide). Direct democracy applications are not viable for various reasons, mainly due to the vast amount of voters and disinterest by the citizens (that's why most prefer to just vote for their representantives). Grassroots/Liquid is an interesting hybrid between direct and representantive democracy. So, have there been any successful applications of the model, and if not then why?
After the Pirate Party of Germany introduced Liquid Feedback (a variant of Liquid Democracy tools) internally and got a lot of press coverage for it, the Landkreis Friesland is now introducing LQFB as a tool to gather more diverse opinions by its citizens.
As this is still an experiment and the first public one it will be interesting to watch how the project evolves.
Press coverage in German about the initiative can be found at ZEIT Online
