You might not “own” your Twitter followers (you can’t take them if you leave), but you get to leverage the platform for distribution. You could theoretically launch your own version of Twitter if you want more ownership - but it’s practically useless if there’s no one there to read your tweets.
This new aesthetic is characterized by disjointed, jarring imagery, including floating clouds and disembodied appendages. I wouldn’t be surprised to spot a melting clock in the near future.
