According to the laws of orbital mechanics, Mastodon can't succeed. We already have a double-star system of Facebook and Twitter, the major and minor component, respectively. Then again, maybe Twitter has acted stupidly enough for long enough that there's a real chance for this to succeed.
@Lisa I'm extremely pessimistic, because I've seen so many alternative networks come and go. And then I heard somebody explaining it in these orbital mechanics terms, and it made perfect sense to me. The time when new stars and planets can form in our system is over, we won't get any new networks anymore. Deal with it. Then again, when I see this, I think that maybe, just maybe, it might work.
You, @drmirror, are a closet optimist. 😄
