Courtney Love knew how to make techie party-boy Michael Saylor feel special on his 47th birthday. The DC-based MicroStrategy honcho, who famously lost $6 billion in one day and is known for sailing with the jet set on the French Riviera, enlisted “every party promoter in the city” to pack the Highline Ballroom with hot ladies for Saturday’s bash. After dinner at Buddakan with 30 friends, he headed to Highline, where Love performed after admitting, “I don’t know who the [bleep] Michael Saylor is, but happy birthday and thanks for the free drinks.” A MicroStrategy rep said Saylor hired promoters to push his new electronic ticketing app, Usher.
