Could be. You're mentioning the Steemit Whitepaper in your post.
I remember reading it and I think there was there a mention that users should vote on about 20 posts a day to keep their Voting Power effective. Anything beyond that would decrease the quality of their votes. This puts things into perspective onto choosing the right content to vote on.
*I re-red the White paper just now but can't find that paragraph to quote it here...not sure if the document changed since I first read some time ago.
