@cpoliticditto I'm not convinced Post.news will be able to replace Twitter, as it certainly will not with its current business model. *No one* wants to pay micropayments for a Twitter replacement. It's also in beta and has been *very* slowly onboarding people.
At this point Mastodon has a head start and actually has *more* traffic and visibility than Post.news. Outside of people I follow here, I don't think anyone I know IRL from school or home, or online via Discord, has even heard of Post.news, let alone set up an account.
In other news: Tumblr is going to implement ActivityPub at some point, Flickr is considering it as well, and Twitter is very possibly about to be banned from or restricted on a certain app store, heralding yet another influx. The Fediverse could end up growing quite quickly before Post.news even gets out of beta.
