To be frank you didn't seem to need it. That's my honest opinion on why no one tipped you. People donate to those who either seem like they're struggling creators, think, young people creating content and while they have stable finances they look like they could use the support to keep that going. And there's also commissions and other features that Kofi offers in exchange for donations. You look like someone who has a day job and whose main career isn't to be a content creator full time, meaning it doesn't seem like you actually need the support. You seem like a corporate person trying to develop a side hustle, and who wants to make money off medium the way we all do.
