I sing, play guitar and run, so can I downvote you? It really has nothing much to do with the content of your posts. It's about getting a fair distribution of rewards. It's supposed to be about what people like.

If you are in London you should get to one of the meetups. We may even meet there. I've met people I've met people I downvoted before and we got along.

BTW I've met @slobberchops and he's a great guy who cares a lot about the future of Steem. The last thing we want to do is chase off good people.
