Kind of like twitter but you’re gunna have to follow some people first, if you like bitcoin go through some of the people I follow it’s all bitcoin and also NOSTR, nostr is the protocol which Damus uses to work, kind of like a system in the background!

Search hashtags of topics you like and give them a follow. Once you're following a hashtag, others who post with a hashtag with the same interest will appear in your timeline, then you can follow them.
