No. Ordinary users is the authors = curators who are below the 25 "successful authors." These 25 authors can write about the weather, about the moon, the frog - bot @wong as well as all members of the network and the entire development team (which is included in your list) will upvote this article. Because it is "their " circle.
It would be nice to do the analysis of secondary authors - the people who actually due weight ordinary people gets good grades, in what genres they work, which direction most profitably? WHAT affect their success (not upvote whale - which ... 0.37% of all participants)? etc.

Although the analysis - your work is excellent. But I would have done the selection users other.
