If it works like email, you’ll miss content that is posted when the app isn’t running. I have a cheap hetzner box going that is running my personal lemmy instance but I don’t think it would work well to have it only running part of the time.

Or just list it as volunteer work…

Agree that one is best I suppose, but on my own little instance I can subscribe to all 3 and interact with all of them just fine. If I had to pick one I would go programming.dev, it would expose rust to programmers not yet using it and would let users on that instance see communities for languages they otherwise might not check out.

yeah nothing wrong with several communities. They all have their place. I’ve been checking out tildes.net. No invite and I don’t know anyone with them, but if its a place I end up spending a lot of my time on I’ll find one.
