For one, the distribution patterns of Whatsapp are far more simple than Twitter. Whatsapp is mostly one-to-one and then one-to-some with groups (with those groups being limited to as little as 100 users at some point, the current 1024 user limit has only been implemented recently). Twitter is one-to-many, with "many" being "several million". But also, how much time did Whatsapp have to get to that point? I'm not saying it's impossible, but that it's difficult and takes a lot of effort that shouldn't be underestimated. > They are taking a lot of users right now. And still less activity than Twitter, and with federation, and with some servers already locking new account creation (mastodon.social, the biggest one, doesn't let you create new accounts). Again, it's not that it's impossible. It's that it's hard.
