In that case there will still be some small payoffs, but only when you vote on very popular posts along with other people (especially when you are early), not just voting for a post yourself. In other words, good wisdom-of-the-crowd curation. Leave lone-wolfing to the whales (and even for them it isn't a good approach). There is also the opportunity to see those with more SP earning more for doing the same thing you are and consider buying some.
