With Dorsey at the helm of both Twitter and Square, will Twitter be a part-time job for him?
Dorsey needs to decide if he's going to lead both companies, and if so, how.
"Dorsey can't be "all-in" on two companies at the same time," said Patrick Moorhead, an analyst with Moor Insights & Strategy. "I could see if one of them was in cruise control mode, but both Twitter and Square need hands-on CEO attention."
Blau said it's unlikely that Dorsey will have two part-time jobs, but rather two full-time jobs.
"The matter is even more pressing for him. How does he manage two full-time jobs?" asked Blau. "A lot of this will be about his team. Who is he going to surround himself with? If he can attract the talent, then he will be successful because those folks will manage the company's day-to-day operations and manage the partnerships. They will be making sure his vision is going the right way, but he will have to turn over that responsibility to others."
