Good use of the topics and tags should help. Both in finding content you enjoy, and helping your audience find you.
I see you've already found the #MinnowSupportProject which will help out a lot.
Otherwise, I'm hoping Steemit improves its discovery features over time so that just a few topics don't drown everything else out.
Thanks so much! The tags are a little overwhelming haha but it's a good place to start thanks for your advice!
