I think it’s a great idea to run a contest to promote these cool new extensions of the Steemit community, and I would definitely participate for whatever prize. BUT I think a cool prize would be instead of a one time upvote or one time transfer of SBD to have a contest winner get plugged into a whale like yours upvoter! Maybe it’s for a month or a limited time, but a lot of us work hard and barely make anything on our posts. You guys can really change someone’s life with your regular upvote! Something to ponder :)
