General advice for people coming over from Twitter and Instagram regarding hashtags:

Hashtags are a useful and important tool here. Clicking on a hashtag will show you results from across different servers, so they're important for federating content and finding people.

There's no need to have loads of tags on your post like Insta to try to catch more engagement, but also you won't be punished for using tags like Twitter.

@Curator Good point. I'm still trying to figure this all out and trying to decide if I need different servers/identities for my different interests. Will hashtags work across blocked/restricted servers....for example like the recent change wrt mastodon.social ?
@kenny If they're silenced, you'll see hashtags from people you follow. If an instance is blocked, you won't see *anything*. Otherwise, hashtags are visible across all servers ^.^
