My heart forever broken by social-media silos, I’m not really interested in using Micro.blog as yet another “Okay, I’m over here now” social network. I get the impression that it has potential for much deeper use than that, if I can only get my head around it.
Micro.blog can be many things to many people which can be confusing, particularly when you’re a very tech savvy person and can see all the options at once. I’d recommend looking at it like a custom feed reader for a community of people you’d like to follow and interact with. Spend some time in the reader and just interact with those you’re following and they’ll do likewise in return.
It’s purposely missing some of the dopamine triggers other social silos have, so you may need to retrain your brain to use it appropriately, but I think it’s worthwhile if you do.
I really need to hash out my domain situation! IndieWeb encourages its memership to claim a single domain and use it as their personal stamp for everything they do on the internet. I, though, have two domains: my long-held personal catch-all domain of jmac.org, and fogknife.com, which I use exclusively for blogging. My use of both predates my involvement with IndieWeb.
Don’t fret too much over having multiple websites. As you continue on the answer to what you want to do with them will eventually emerge more organically than if you force it to. For some thoughts and inspiration, check out https://indieweb.org/multi-site_indieweb.
