Twitter was great. But now antisemites, haters, chauvinists and much more.....this kind of folk took over.
that is the thing with free speech, however. It's like "free money" in that your enemies should be allowed to use it.

Let them all speak, and let them all transact value. Nostr - Bitcoin - changing our society a note and a block at a time...
