Jack Dorsey responds to questions about his role at Twitter… kinda.

A day after a New York Times profile on Twitter CEO Dick Costolo made waves for hinting that the service’s co-founder had a reduced role at the company because he was “difficult to work with”, Jack Dorsey has taken to his personal blog to write a quick note to describe his work at Twitter.

It seems that Dorsey, who co-founded Twitter with Ev Williams and Biz Stone in 2006, confirmed that he is currently spending most of his time at the other startup he helped found — Square. He only visits Twitter on a Tuesday afternoon, and reiterated in the post that he holds an interim position there:

In Spring of 2011, Dick asked me to take an operational role overseeing product, design, and brand. Our shared goal was to get those organizations back under him as soon as possible, simply because it was the right thing to do for the company. We moved all of my reports back under him in January of this year after leadership was firmly in place.

This allowed me to focus on refining our brand and logo, to work more with Dick and the leadership team on our direction forward, and ultimately return the majority of my time to Square, where I’m CEO.

They didn’t disclose this publicly, he writes, because “it’s not what people using Twitter every day care about”. But if you were hoping for him to respond to the line in the the profile which states he was given a reduced role at the company “after employees complained that he was difficult to work with and repeatedly changed his mind about product directions”, you’ll be disappointed. In the post, he suggests that the arrangement was decided on by mutual agreement.
