Is it 1 million daily users, 2 million, 5 million, 10 million, 20 million, 1 Billion, etc. Nostr has already won in my opinion, it’s the only social media that I’m aware of that lets you self host your own content, and media on your own server. Sure there can be some integration improvements to make this task simpler, and even benefit users on conventional social media. For example, something that I would say that would improve Nostr, is embedded backups/mirrors, the video runs through the primary service, in this case youtube, it would allow the user to get the view on YouTube, & make money from YouTube but then mirror it to Nostr if the video was ever deleted on the main service. Because right now our current method unfortunately steals that view away from the original content creator. Nostr needs content, and more precisely original content but currently we are forced to reupload content that we enjoy due to the lack of non-Bitcoin focused content creators.
