Does the Twitter CEO’s departure signal a platform identity crisis? | John Naughton

Jack Dorsey will no longer steer the company he founded, but is this due to stagnating profits or a more fundamental change of direction?

So Jack Dorsey has stepped down as the CEO of Twitter. This means that the company has had four CEOs in its 15 years of existence, with Dorsey occupying the role twice, but in all that time it's had only one business model, which may largely explain his departure.

There are interesting parallels between Dorsey's relationship with the company he co-founded and Steve Jobs's with Apple, for both were ousted at one stage by their board colleagues and were then brought back to rescue said colleagues from their incompetence.
