Mastodon's official stance on Threads
(blog.joinmastodon.org)
This is a most excellent place for technology news and articles.
Remember what Google Groups did to Usenet? We should be wary.
It didn't do anything. Usenet still exists and is active in some circles. It's not very popular, but it's as alive and well as it always was.
I should think there are many people who think Google Groups is Usenet, and they have to register with google to post on there. Recently I think they have removed the option to view the source of an article.
