New here, but it doesn't seem right to have any selling or buying votes. I am also, thus far apprehensive to down vote anything (not that it would matter) because I dont understand what it would do. Why can rewards be based on creating something good and useful (for example small advertising that cuts out the middle men such as google or facebook, based on views and likes by steemit users and the casual people who happen to find the content on a search engine). The steampower holder would still get interest or a proportional share or created blocks, but not have total control over what qualifies as good material. Not even sure if changes are possible, or if details like this are locked in forever. Just random thoughts from a new user, take them or leave them. Also, If your content gets massively and unfairly downvoted, cant you just post it again and hope for the best?
