I can't reply to js8 due to the indentation level, but that's somewhat new to me.
Semi-direct democracy when people use the term seems more related to some occasions where everyone has a chance to participate in a decision, through an initiative, referendum or similar. Wikipedia describes it like this.
But it does not talk about cases where you could opt-in to vote on every decision, and if you did not your representative would vote for you.
Basically, you would chose a representative like you do in most countries, which would have the n votes of the people that elected him by default, but at any time you could say this vote is for me, your representative would have minus one vote and you could vote anyway you feel like.
This seens a bit more manageable than what jadbox describes in that you do not have to track potentially million of representatives.
The biggest issue would be on how you could vote, because the window has to be relatively short for things to happen, but long enough to allow everyone that wants to to vote.
