They aren't celebrities. They aren't just people with a following or a popular channel. They are specifically people with a following that are successful at converting sales.
Unless you have something interesting to say on the matter, I don't think this forum needs more "le wrong generation"[0] posts.
Artists, creators, chefs, bloggers, travel junkies, etc. Whatever it is that they actually do.
You do not just become an "influencer", instead you gain influence by way of gaining a following for doing (and being good at) something. The term is definitely overloaded and mostly pointless now.
The term “influencer” is such an eye roll to me.
