What other acquisitions by Facebook resulted in that product falling apart? Instagram is still doing its own thing, also Parse as well. People need to get over whatever negative emotions they have towards Facebook. It's like they hate Facebook for reminding them of a bad breakup. Congratulations to entire Oculus team, that's an exciting acquisition and I look forward to what this infusion of cash will do to the future of an already incredible product.
