In its heyday, before the most recent acquisition, Twitter was really good for local info (ignoring celebrities, shitposting, and the like). Not just news but announcements, alerts, and other local stuff if you followed the right accounts.

Mastodon is cool, but it's hard to consistently find that local info. Bluesky seems like it has a chance of supplanting Twitter in this way, but it's not there yet. Some of the accounts I used to follow on Twitter are on Bluesky, but they don't post. If they started, I think they'd get tons of followers now.
