Honestly, when I do come across some ephemeral junk from 30+ years ago, it is kind of a delight. Even tho the object itself usually serves no purpose now.

Yeah, my room is a mess, why do you ask? <.<

Think of it like email. We don’t exactly worry about degradification of email. Instead we have to worry about gmail, or proton mail, etc becoming awful.

In the same way, it’s less that Lemmy might go downhill, more that maybe individual instances could. In which case, there are various degrees of how to avoid an instance. Leave, unsubscribe, block, defederate, etc.

For example, Meta created Threads and tried for a while to integrate with Mastodon. But Mastodon is still pretty much the same afaik. Many instances defederated from it, other people just ignored it, some people I’m sure were happy to communicate with a wider crowd.

Of course, the idea breaks down in a couple ways. Communities and communication on ActivityPub isn’t really the same as email. But mainly, email is kinda bad these days because of big actors, bad actors, and just ubiquity. Not sure how to prevent automated spam from clogging up every communication channel.

Love how much stuff Wikipedia has out there!

Don’t get expectations too high tho - materials are there, designed to guide you through learning, but you’ve very much self-directed. Be prepared for plenty of interesting courses to show up in the list, but to actually be incomplete stubs. You can look for courses by completion status to mitigate that. And it doesn’t have the same level of editor engagement as Wikipedia, so not everything will be as fleshed out or as correct.

Wikibooks is also cool, if you’re into this stuff. Same caveats apply, many of the books might be incomplete or outdated, but a good resource anyway. And don’t forget, if you want to learn about something, some thorough reading in Wikipedia itself is probably a smart primer.
