"I'm pissed about what I did with Twitter," Wine Library TV founder
Gary Vaynerchuk tells The Deal in this video interview. Vaynerchuk
regrets missing the opportunity to invest early in the
venture-backed microblogging service despite being bullish on it.
Eventually he bought some stock in the privately held company from
an early holder of it but says he learned his lesson about angel
investing. "I'm sitting pretty," says Vaynerchuk. "But I could be
sitting obnoxious if I had acted on my intuition." Today, the
colorful wine retailer and video blogger sports a startup portfolio
that includes multimedia microblogging service Tumblr,
picture-taking social network DailyBooth and location-based social
networking game developer Gowalla.
