I am very well aware about the lack of algoritm and how Mastodon works. But the issue is not for me, I like Mastodon! And I don't like Twitter at all. But it is for Average Joe, who needs to come over in order to replace the place of Big Tech SNSs.
Growth is not the only, nor even main, metric to measure success of fedi.
If the Fediverse just wants to exist stabely, even be mentionable in size, it is not. But to take over from the Big Tech SNSs, it is. People are where other people are. And that's what the topic was about, replacing Big Tech SNSs.
This is false. I follow a couple of thousand people and have an interesting, diverse, funny, and informative timeline. Very few accounts I follow crosspost Don't get me wrong, I enjoy Mastodon. I also talk with some i teresting people there. But I still cannot follow any of the local news there without bots that copy Twitter. I also know companies who have accounts on both, and beside of reactions on what people say, their updates are cross-posted (manually). Not everything, but if you want to follow companies and people outside of tech-related scenes yoh already need to be happy if they have a cross-posting Mastodon.
For me, it's enough. But for Average Joe, who wants to commend on their favourite influencers and use it to talk to custoner support of delivery coyriers and stores they buy from, it is not. In fact, customer support is the only reason I have a Twitter account.
That takes more time, than hooking people on endorphin/noradrenalin high and slick interfaces. Sadly, Average Joe just want his endorphin kick 🥲.
