As a general idea, I'm all up for using the SPS to create added value. And marketing is a way of doing that by changing the image of Steem, creating awareness, and bringing in more users, investors and potentially new businesses.
I have a question and a concern here. The question is if we should do it after launching SMTs or start now.
The concern is about the inflation of SBD. We don't have a strong sink for them, other than dumping on the market or converting to STEEM (and if I'm not wrong, at these prices it's still unprofitable to convert). I wish SPS would offer alternative payment options, if not now, in the future.
I think we definitely we need to start the ball rolling now. It would take 2 months minimum to get this up and running. SMTs will be definitely be part of the marketing message, but there must more than just SMTs. Putting all the eggs in one basket won't be ideal.
Re the SBD issue, I don't know the answer. But we have to work with what we have.
