Well you now have my tiny fish vote.
For what it's worth I recommend @themarkymark for one of your open votes. His blog would do a better job of illustrating why than I could. My impression is that he works daily to curate and improve the platform as well as running servers, teaching people about Steem and programming with his posts, and running a bot that I think is a force for good. He and @lukestokes.mhth were my first two witness votes, because I randomly stumbled across some content that taught me more about the platform and inspired trust.
Unlike jerrybanfield (another early vote of mine), these two did not disappoint.
