As a tech blogger for VentureBeat, Anthony Ha is always an Advocate for something. Currently, his obsession is the online travel service Hipmunk. "It's the only tolerable way to book travel," said Ha. He likes the way Hipmunk searches, sorts, and displays his travel options. Beyond writing about Hipmunk in VentureBeat, Ha will occasionally tweet about Hipmunk, but that's usually out of frustration when he can't find the flight he wants and is forced to go to another "lesser" service.
