I think that a proactive step for the SPS system would be to plan out all possible blockchain conferences in the coming year (2020), then begin organizing around them. Pinpoint the location and from that, make "missions" that individual steemians that are vetted according your qualities, CAN propose to represent STEEM in that event.
I think that Steemit, Inc SHOULD be involved in some form of another. Either logistics help or kick ass designs for visual representations. Some of these things require skills that many on the Steemit Inc steem may already possess (no need to hire more).
Additionally, if they are displyed are "missions", individual steemians could also get on board by making posts and sending the profits to complete the missions.
I for one, I think could be a solid Representative for SPS. I am located in Central America and I do have experience in public speaking and relationships in the Academia world. Specifically Austrian Economics.
