I have started a similar thread at
http://forum.citizendium.org/index.php/topic,2733.0.html Wow, I didn't think I'd be an example of someone who would get this honor. I have always felt my work was mediocre at best.
Anyway, I think it should be open to all contributors, with an emphasis on newbies.
Expect? To borrow from the wisdom of Monty Python, "no one ever expects the Spammish Inquisition".
There have been a few Citizendium authors who created a featured article, and, at least in one case, where I sent some encouragement. I'm not quite prepared to recommend a Citizendium cheerleader squad, but I'll merely note that different sorts of things will encourage a student (at different levels), an academic, a professional (giving back), and a retiree. Just to offer myself, I consider myself a professional giving back, but underemployed -- it's a way to keep up my skills.
