So the true thing people say is “we are the algorithm” — you’ll run into people posting about interests you have (via hashtags) and people who those you follow are interacting with, either through conversation or through reposting their stuff. 

I’ve never had Twitter but I think this way is good enough for me. The experiences I’ve personally had with algorithms elsewhere have led me not to trust them to actually account for my real desires of what I want to spend time on.  YMMV!
