A boring #tip that I'm sure every new person knows about but just in case you don't...

On Twitter, you could only follow people.

Here (by 'here' I mean #Mastodon's website specifically, not seemingly Pleroma) you can also follow hashtags. Just search for a hashtag and if you like it, hit the follow button, top right.

@james thanks for the tip! This only works in browser, not app (that I know of) if anyone was wondering.
@davidwoje @james I can confirm that it definitely works on Subway Tooter and Fedilab - both Android apps. Work on Tusky too, except Tusky only allows 5 tabs on your main screen.
@shrikant @davidwoje I'm not talking about search tabs, like Tweetdeck or these apps; I'm talking about following a hashtag, so that everything with that hashtag appears in your Home Feed. But those are cool too!
@james Ah, got it! I didn't know that! Cool find, #TIL! Thanks! :) @davidwoje
@davidwoje @shrikant @james I follow hashtags. It is like following topics like #photography #obsidian #podcasting

Only problem is hashtags are not across fediverse. They are limited to the instance.
@james @shrikant @jjude interesting. May be good though to not flood your home page with tags 🤷‍♂️
