There are some local news sources that post info about local traffic issues, emergencies, etc, much faster on twitter than elsewhere.

Also, there are some experts on international topics who write articles elsewhere, but still discuss those issues with each other on twitter. There’s a list of english speaking experts on ukraine I keep up with. everyone’s migrating, but not as fast as I’d like.

I use nitter for that stuff. Here’s hoping they move soon, but people who know what I want to know aren’t always good at social media.
