I think that @lordbutterfly can agree with me on this that Hive kind of needs a similar strategy deployed as well (not many are aware of what great marketing is, how costly it can be, and why it is so important to do this right of the bat). This is pretty challenging and can get quite complicated on Hive due to the amount of different cultures, beliefs, or even the tech development of a country and so on.
Haha I feel this! Trying to champion real marketing among a sea of skeptics is always an uphill battle. Doesn't help that there's a lot of scuzzy/scamminess in so many "agencies" out there like you alluded to.
For the Hive masses, my gut says that best educational content in this regard would be detailed breakdowns of things that did work (in keeping with the theme of this post). Or at minimum, detailed breakdowns of things that were tried and failed, and an analysis of why it failed, etc.
You rarely get that kind of introspection even in professional marketing firms though... so a challenge indeed. 😬
