I have mentioned this before, but it is worth a mention again.
Many early adopters were users of other platforms, and likely regularly engaged in self promotion. As the followers of the Witness/Influencer crowd migrate to the Steemit platform, this group of "new" self-promoters will have to cut their teeth on what it means to 1) create quality content, and 2) self-promoters in a way that also promotes others in the community.
Your post demonstrates a "lead by example" approch to helping others understand the "why" of self promotion.
