I've stopped self-voting as I prefer to add value to the system at the expense of losing a little income for myself. Even if self-voting was banned people could still do it via other accounts they control. I believe that especially at this stage in the evolution of Steemit we need to be encouraging others and building the platform. If it goes viral and Steem goes to $100 then we'll all make much more anyway. It's about taking the long-term view and not trying to milk the system for all you can get. I appreciate that for some people a few dollars from here can change their lives, so they may abuse the system, but we can try to persuade them that another strategy could be better for them. It's all a big experiment and we have to see how it turns out
