Look, you want me to get excited about Mastodon? Show me something exciting I can do with it that I can't do with twitter, instagram, or Snapchat. Is there some triple-I indie game that Mastodon will allow me to play in my browser? (Or triple-A non indie? I'm not picky. Just don't show me a point and click please.) Post the link for that game, you'll get a lot more people trying Mastodon. Alternatively, is there some new and novel porn that Mastodon will allow me to access? Or is there a new generation of FIFA stars on Mastodon? Or new generation of NBA stars? I mean, even a new generation of "It" Girls chasing NBA stars would be better for attracting users than "thoughtful and local uncommented retweets". Which is not only what you're asking me to get excited about right now, but is likely not even true. Boosts will be no more thoughtful than retweets, likely a good deal less thoughtful since Mastodon seems to be on a road that relegates it to fringe groups.
Right now, it's like buying a large tract of land in Kansas and saying that you've started a new municipality. No we don't have beaches, or theaters, or parks, or much of anything else, but everyone here is more thoughtful. so we're much better than Miami, San Diego, or Minneapolis.
I mean, it might work? But I think Las Vegas hit on a much better method of populating empty area by just saying, "HEY! We've got gambling and naked women!"
