@jwurzer I recall that @macgenie had a good piece called Where Discover Doesn’t Help that may also be useful to you. I had responded to it with some related ideas around Micro Monday. Another good place to find people is to visit the micro.blog profile pages of people you do find interesting and then click through the “Following XYZ users you aren’t following” to see people who may be similar.
To some extent, just like you did with Twitter and all your other social networks, you’ll likely have to (re-)”build” and “discover” your audience and people you want to interact with. The nice part about it is that it’s built on open protocols, so as more and more sites and services support them, you’ll be able to interact from one place instead of the typical 4 or more.
Personally, while I highly leverage m.b. and its many discovery aspects, I do it with my own feed reader where I pick and choose who I follow (whether they’re on Twitter, Instagram, micro.blog, or their own site) and then read them all there. Then I’m using my own website to collect, write, respond, and interact. It’s taken me a while to reframe how I use the social layers of the internet, but ultimately I find it much more healthy and rewarding.
