It's really tough starting out on Medium. Getting anyone to actually see and read your content is a win.
After a while, you will eventually find your own audience, and claps, highlights, and comments won't be so difficult to find.
If you want to check out some people who write great content but also support others, you can look at my June earnings report I published yesterday.
You don't even have to bother reading it but just scroll all the way to the bottom, and I included 14 of my favorite writers on here. They will most likely support you if you read and comment on their articles. (Of course, be genuine about it)
