Mobile video sharing app Viddy has looked like a bit of a mess lately. CEO Brett O’Brien was canned, and the company this week laid off a third of its staff to streamline operations. (Not even one year ago the company was on a tear, at the top of the App Store, and with $ 30 million of investments in the bank). In the midst of this week’s turmoil, the company is today launching Viddy 2.0 for iPhone, an update that brings in one of Vine’s best features: one-tap shooting and editing. It’s now easier than ever to shoot videos with the app, but was that ever Viddy’s problem?
