I'm not using steampeak, but I'm open to it! Not sure what it is exactly. Do I just log into it?

I see it as acting like a sub-reddit would. I post official things to it, and in a beautiful scenario we would get some fan art and interaction from subscribers like we used to get back when steem was 2+ USD and everyone was posting like crazy.

Do you think that's a good use of the community tool, or am I using it less than effectively?

If 90% of the rewards go to a community owner, wouldn't that mean that people aren't incentivized to interact with content, because curation rewards would be so low?
