Interests are important. If Jane is a well informed rich person, and you are a poor person, handing your vote to Jane might not end in a solution that is optimized to your interests.

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.
