Even if you get to where your vote is not worth 1 cent, it may be worth 1/2 a cent. That may not seem like much, but if two minnows each worth 1/2 a cent vote on a post - then it adds 1 cent :)
At that level though, it doesn't matter a whole lot either way. As I said in the post, it is best not to get too bogged down in the details of the math, curation rewards, and voting power. Focus on engaging with the community and voting on the stuff you like :)
