Why #Mastodon is absorbing most #twitter users on the #fediverse? I haven't tried other alternatives that have been using #ActivityPub for a while, like #Pleromo and #Pixelfeld. I'm seeing a push to new softwares that use the same protocol, like #Takahe. I discovered just today #Calckey, which has the so demanded quoted sharing.

So why the boom came to Mastodon? Is there any chance of Mastodon, some time soon, be substituted by a fork or one of these on going and in progress alternatives?
