We all make decisions that we regret. The advantage of Interactive Democracy is that each voter is a small cog in an enormous machine with perhaps tens of thousands or millions of similar voters. A machine that requires a significant majority to ratify a law. So if you get it wrong (change your mind after the poll), there's no need to regret.
The corollary of this is that there are less than 650 voters in the House of Commons. Make a mistake there and it can have a much bigger effect.
