Good question! In my opinion if I had such big HP and don't visit daily or let's say hourly hive blockchain then I'd decided to use bot or maybe other tools to automate my votes. Espessialy to vote for my favorite authors or bloggers. In other case I'd like to vote manually after reading carefully every post which I decided to choose!
Anyway I think I'd vote not for all 100% but use part of voting power to reach more people and support them. Of course excepting that moment that I can find maybe that some post is really brilliant and it deserves full vote!
