Nice. When I am teaching students in our intro class that everyone takes it once regardless of skill, I can always tell when someone has skated as a kid (or done other sports like skiing) even if it's been decades for them - it's just much easier to return to than to start from scratch like I did.
Roller skating. In that community my skill level is nothing special. But it's not a common hobby to have at all these days (at least where I am) for the average person.
This is all very true. I didn't mean it wasn't a profound message - just that the profound can come from odd places. It was an excellent episode in my opinion.
Yeah - in the terminology here it would be more like a whole group of communities (since we call each "topic" on an instance a community) but yes.
Admins can (and do) also block individual communities on an instance that is still federated, such as lemmy.world blocking!piracy@lemmy.dbzer0.com but leaving most of the rest of dbzer0 connected.
Basically "yes" to all of the above, including "not all connected": Most of them are connected to each other, but some are "defederated", for example there's one called Beehaw that isn't connected to lemmy.world and some of them have chosen not to connect to lemmynsfw.com for reasons.
There are two unexplained phenomena that I currently believe in (but either could change at any time - by being explained or by being shown not to exist.)They are dark matter and dark energy.
... Is it not?
Being a grain (or even specifically a "Cereal grain") doesn't exclude it, see corn.
