So I'm here. But even though my friends are awesome, I don't have any new ones I've made on Mastodon (unlike Twitter), and it is overall pretty boring and unlike Twitter it makes building a network feel like work. At the same time, it is of much less use for work. I have almost no Africa network, I have little interaction with journalists, and because the network is more closed, I learn less.
Whatever. It's fine but it's not a substitute for Twitter at all.
