I think on a very small scale it can work well. Farming communities. Maybe a small town. A union maybe.

It can be useful. But in many cases direct democracy is just going to amplify ignorance and be guided by emotion rather than logic.

Like for example. If there were a major vote about an energy related issue regarding something like nuclear power and the benefits of using thorium or something, personally I would like to delegate my vote to someone who is a trained scientist and more educated and informed on the potential ramifications and issues related to thorium. Not that I could spend more time learning about myself, but I'm not a professional scientist and I'm not arrogant enough to think that my opinion should count as much as someone who's dedicated their life to the study of science.
