One more tip for newbies (which, er, I just figured out yesterday, so it's not like I'm a pro at this): Mastodon has a "lists" feature, so (for example) I created a list of journalists, and then I can just open that list and see what all the journalists are talking about.
Next working on lists for law, policy, and academia.
And in the advanced webview, I can set up all those columns next to each other.
It's... nice.
