I don't know what I'm talking about, but judging from the fact that Ev Williams founded or co-founded Blogger, Twitter, and Medium, perhaps he was the real visionary behind the idea. That's three different "write stuff online and share it" startups. He clearly understands social media and blogging and micro-blogging. Maybe Jack is more of the 'biz guy'?
My take on the founding of twitter is that you had a bunch of people and no clear leadership, and that different people had different opinions of what twitter should be. That ambiguity has undermined the platform from day one, no focus, no clear mission, no clear plan on how to spend their money.
