I misunderstand the point of this BTW. How does this benefit the end user?
You vote for delegates that you trust so that they can participate in securing the network, essentially performing the same role as miners do in Bitcoin, producing blocks. There's a subforum devoted to delegates where they (we) introduce themselves and make a case for why you should vote for them.
The benefit for you is a secure network, and since your stake is quite big, it's even more important that you vote
The more people participate in voting, the better the security of the network because it becomes harder and harder for a big stakeholder to vote in "nefarious" delegates.
