I get that Mastodon has a Twitter-like goal, but since it's federated does that mean I have to join specific instances to find out about international news, US politics, etc.? Honest question, since I've not tried Mastodon. I thought Threads was not supposed to be about news [1], and at any rate its traffic is dropping. CNN is probably one of the first-movers in the news space, but surely it's behind Twitter in terms of timeliness. 1: https://www.theverge.com/2023/7/7/23787334/instagram-threads-news-politics-adam-mosseri-meta-facebook https://www.theverge.com/2023/7/7/23787334/instagram-threads...
