I wish communities could be grouped in some way.

or not 🤷‍♂️

Sure it's more practical, but your whole community (as in "people") is now centralized on a single point. If you have a single one "gaming" community, and it disappears or is taken over, you lose everything and need to start over from scratch. If you have 3-4 communities spread across different instances, if one of those communities become unusable, it's easier to abandon it to become active on the next one.

Decentralization is not a silver bullet, but as we've seen during the last year with Twitter and Reddit, it's better than the alternative. Nothing prevents you to subscribe to several similar communities, each with its own flavor, and participate in the one(s) you want.

The boy scout technique: fix your types when you're working on a bug or a feature, one file at a time. Also try to use unknown instead of any for more sensitive parts, it will force you to typecheck.

The kid that tried to kill 2 people by throwing them bricks, paint buckets, and broken glass is now a spokesperson for Facebook? How surprising.

Yes there's no difference between a picture of a steak and fries on a plate, and a kitten being tortured then burned alive. Absolutely the same thing.
