I think influencers are a thing. What the threshold is, I don't know.
But maybe it's one of those things that work when it's unstated. Soon as you declare yourself an influencer, then unless you have bona fides, you cease to be an effective influencer.
Influencers in tech: Woz, Jobs, MarkZ, Musk, Ng.
Influencers in other areas: LeBron, Kardashians, Obamas, Sanders, Trump, Brady, Kanye, Jenner.
Most/all of those are influencers not because they seek to do that explicitly, but because it's a byproduct of other achievements.
When it's your main thing, then you're not so much an influencer but a promoter.
