Twelve years after Barack Obama addressed the Democratic National Convention for the first time, he took the stage on Wednesday to endorse Hillary Clinton for president and delivered yet another convention speech that garnered rave reviews. Indeed, it was hard to find any prominent Obama detractors snarking about the speech on Twitter afterwards.

Earlier in the evening, former New York Mayor Michael Bloomberg's endorsement of the possible first woman president was  a bit more reluctant. (He did, after all, seriously mull a third-party run this year.) Bloomberg's phantom candidacy stirred up a frisson of interest among tech and/or business types, and his words last night still resonated with The Kitchen founder and brother of Elon Musk, Kimbal Musk.

But others kept their comments to the current President, and the woman who might replace him. Shonda Rhimes voiced regret to see Obama leave the Oval Office.


And Mark Cuban was already thinking ahead to when Trump and Hillary will face off at the debate podium. (Or not.)

And some keyed off the valedictory air of  Obama's speech to start thinking of his legacy. Among them: former Twitter CEO Dick Costolo, who compared Obama's ultimate significance to his party to that of another iconic President.
