I've stopped participating. I still stop to see what you have written occasionally, but maybe you aren't hearing from people who left the platform...
I didn't want to 'build community', or buy a lambo off my steem - just wanted to use it as a blog.
It didn't really do well as that.
I'm about to start a blog through the winter, detailing 90 days of running in a northern environment. It won't likely have any commercial effect, but only a curiosity for my friends and other runners. I'll likely use wordpress over steemit. Various reasons for this, but I'll try to pop back in and answer if you have questions.
I love the idea of steemit, it's free speech support was pretty exciting. Later, I learned that money will provide something very much like censorship, and it took the shine off a bit.
