Your more recent posts, however, have been doing a lot better.

Keep in mind that discoverability is not a unique problem to Steem. Every other social platform out there has the same issues: saturation.

You are competing with millions ( billions? ) of online users. Steem is no different, just a lower number, but still quite large!

Hang in there. It takes a while, a long while, to build an audience. But your writing seems solid & your chosen topics have large interest. You can do it :^)
