I think liquid democracy is probably the end-all-be-all of voting systems. It provides maximum participation for those who want it while at the same time allowing maximum delegation to those who don't want to participate. It also allows instant changes to the legislative group on a per-person granularity. You literally can't do better than liquid democracy.
I'd love to see a town or city experiment with this, cause good luck explaining this to an entire state without solid working examples. Are there currently any jurisdictions that use a system like this?
