This is so important.

How about running a Hive Agency, similar to what influencer agencies do? The agency makes a deal with the content creator to promote or display a product for X amount of dollars paid in HIVE.

This can be a temporary solution, before rolling ads in the platform, and probably less obtrusive in the long run.

CTA's can be added to posts and tracked in the normal way with Google Analytics, or platforms like @3espeak can add a CTA button Overlay.
