Talk to like-minded people - like you and me here, sitting on Fediverse, discussing tech. Help set family and friends up with access. That's what I do today with my Matrix server.

The rest of the world rarely have anything good to say.

Well Meshcore only recently arrived here, but you can still reach Latvia from southern Finland. Not completely effortlessly though.

I'd like to kick most of the world out of my bubble anyway. Most people just annoy and depress me.

And talk to who? You (and I) and the 0.001% can ham it up, but the rest of the world will be living in a different bubble.

And just talk btw, no bandwidth for anything else

They already are though.
