I think I'm both, and yes, at times self-voting seems a little odd.
I love to create fitness content and hope to steer my blog that direction going forward. My primary reason for participating on Steemit is as a business/income stream. But to do that effectively on any platform you have to provide value first. You can self-vote all day on a worthless post and not get very far as a business. To that end, if you provide value to the community there shouldn't be any reason not to allow a vote for your own content.
