nostr:npub1yck44z5zqxmwpqzqs75ay6ffjdw843ng9p6mz0lzfff3fgz2djlsngujmw By "using it right now", do you mean you're able to stay in the same thread w/ me w/o mentioning my username? If so, that makes sense — since Twitter had the concept of "in-reply-to" threading that allowed posts to... be in reply to another thread, and it wasn't necessary to mention the OP.
