One thing that's clicked with me just recently is how easy it is to follow/share stuff you like from other parts of the federation here.
Want to follow a @pixelfed account you like, but don't want to make an account over there yourself? All good! Just pop 'em in the search bar here and follow from your existing account.
Want to share a cool video from a @peertube account? Follow it from here the same way and their videos will be available to share straight from your timeline.
