I must confess I've done a couple posts pumping up Steemit but they were genuine. I get your point though. It gets annoying after a while when you've been here seeing the same crap over and over again. As @ender said, Steemit could use a way to pin some of the better how-to Steemit posts so that users don't keep asking the same questions. Otherwise we do kinda need one of them trending every day so the new users have an easy way to learn about the site.
Edit: And your wish is granted, I complained about a problem with the platform.
