>He used Twitter and Medium because people follow him on those platforms.Of course, yes. That's where the audience is. I'm pretty sure we all know that. (A small nitpick -- Bezos actually didn't have any followers on Medium before his first and only Medium post[1]. Therefore, he could have directed the Twitter link to a blog his own domain "jeffbezos.com" but he chose not to do that.)
>You are overthinking this.
Yes I am! And I want others to overthink it too. The point of my comment is to dissect the topic of this thread "Always Own Your Own Platform" -- by using a prominent counterexample.
JB didn't follow Sean Blanda's advice[2]. He also didn't adhere to the POSSE guideline. Why?
("Because JB's followers are there.")
Let's try to break the infinite loop of nonproductive discourse. _Why_ are JB's followers on Twitter? Even if they're on Twitter, why does JB even _care_ about that? He could have just followed Sean Blanda's advice and posted to "jeffbezos.com" -- but he did not. Let's overthink the reasons why Blanda's advice was not followed.
