I agree I wouldn't want to get tangled up in too many initiatives at the outset. I don't want to limit the focus of the community too much because I fear the Steem user base is still quite small and dividing aspects of fandom would result in a low population group. That's why I envision the encompassing framework of a convention.
The community could vote & steer the outreach and growth efforts though. Certain periods of time may be devoted to developing areas of the "con" one at a time.
