I had the same question. I went to her Medium profile and see that she is doing a lot of writing for a publication that I had not heard about - Towards Data Science. But I would be curious about the approximate percent of her income from Medium versus elsewhere. And yes, the trajectory of her income would be interesting. Was the $2900 a big jump up? Did it take a while to get over $100 in a month? Although we aren't supposed to compare ourselves, it's sometimes helpful.
