That is a good choice. Find someone who has something to sell or market such as a book, an album, a film, or someone who has important research they want to discuss. You can approach them by offering them an audience which to an artist or writer nothing can be more important. You don't have to give them anything except the opportunity to introduce themselves on a new forum. Chances are they want to improve their Qscore if they know what it is and if they don't then why not tell them? Then of course Steem benefits from it too. I also know Qscore isn't the only metric but Klout and others exist so any metrics can improve things for both the artist and Steem.
