Looking at the negative opinions on mastodon , my take is that it’s only bad for writers (some may say spammers) who seem to want to subject the world to their writing (perhaps spam) and not leave a choice to the user. I prefer to keep things somewhat as they are, if I want to find some spam, I can go looking for it, if I want to find a blogger, same, it’s just a matter of looking at the local and global fields and maybe public figures should simply publish their id’s in their web page for people to find. Not having a stream filled with spam or stuff I’m simply not interested in (I can look at the local and global streams elsewhere) is what I would call efficiency in this type of app.
