I honestly do not think I would change. I would still vote primarily at the 50% level, and still for 15-20 post a day. I have a few people I give 100% votes to, and everyone else gets 50%. I am always happy with any vote I get, but not all votes are the same. I may not be "happier" with a big vote, and then again I may be. If it is a vote from someone I follow and like, or from someone that is known for being nice, yes I would be very much more happier with a big vote from them. (I once got a $10.00 vote from @grumpycat, I kind of miss his views and view points on steemit).
So being able to give out a $1.20/$2.40 vote to the people I follow, the tags I follow, I think that would be fantastic. Yes I could lower the percentage and spread the net wider, but I like the tags I follow, and the post under those tags. I do save some votes for new post or people I have not voted on before, but spreading the vote to thin is not me.
Lets say a small town needed a new water treatment plant, it was a town of 30,000 people. Building this treatment plant would cost 30,000,000 dollars. Someone with big pockets give every resident 1,000 dollars to build the water treatment plant, but they do not need to use the money for that purpose, it is just suggested. Do you think that $1,000 in hand now to fix the bathtub, or the car or the what ever, would not out weigh the water treatment plant?
I know the tags would end up being flooded, but I would be careful about the votes I gave out. When I run real short on Vote Power I have dropped to 25%, ant that is what it was asked for the #tenkminnows boosting post. Featuring 20 people at a time that would be 5 full power votes, a pretty good guide to help build and still leave votes for my regular accounts.
So I guess, no real change in how I do things, I just do not think I would have time to find more that the 15-20 post a day.
