Liquid democracy is the idea that individuals should be allowed to transfer their vvote to some other private individual, whom they judge to be better informed. It is not representative democracy, because there is no fixed pool of representatives…anyone can be a proxy.
Liquid Democracy sounds OK if everyone is equal and all transactions are voluntary,, but those are naive assumptions. I can envisage situations, where, eg, some Victorian style paterfamilias browbeats his family into handing over their votes. Perhaps listening to well informed commentators and then casting your own vote is the
low hanging fruit here.
