President-elect Donald Trump held a summit today with leaders from the tech industry, but there was a key omission: Twitter. Reuters reports the meeting included Amazon CEO Jeff Bezos, Tesla and SpaceX's Elon Musk, Apple CEO Tim Cook, Facebook COO Sheryl Sandberg and Microsoft CEO Satya Nadella among others. Not at the table? Twitter CEO Jack Dorsey. The transition team's official reasoning is that "the conference table was only so big" and that with a $13.85 billion market capitalization, Twitter was "too small" to invite.
