I don't get it. Right now, an ostensibly fair and educated person could tweet his or her vote recommendations, and people could choose to vote according to those recommendations. Presumably a lot of voting is already motivated by trusted recommendations (even if it's just party lines).
Agreed. As described, it has the worst aspects of both systems; all the coordination problems of direct democracy, because anyone that feels inclined to vote on any particular issue has the right to do so, and most of the problems with representative democracy because a huge proportion of people will feel inclined to delegate [most of] their voting to well-funded and persuasive people or groups that may or may not be sincere about what they actually represent.
If those casting the delegated votes get secret ballots too, you can throw in a new problem: undetectable and potentially indefinite subterfuge...
