The conventional use of Liquid Feedback is describe a new form of interactive democracy.
The basic idea is a democratic system in which most issues are decided (or strongly suggested to representatives) by direct referendum. Considering nobody has enough time and knowledge for every issue, votes can be delegated by topic. Furthermore delegations are transitive and can be revoked at any time. Liquid Democracy is sometimes referred to as Delegated or Proxy Voting.
In IT terms, Liquid Feedback is what happens when a vendor takes you to the pub.
Of course, this is an almost certain guarantee of positive feedback so as to ensure that future feedback opportunities will occur repeatedly.
