I didn’t get a chance to see all of Zuckerberg’s testimony, but from what I saw and read, he seemed to use a strategy of deflecting questions and downplaying what Facebook does. He also seemed somewhat ignorant to the core technology that Facebook uses. Either he really doesn’t know the technology that we’ll, or he’s faking ignorance. How this plays into social media and Steemit is unclear, but I think it helps open the door to Facebook alternatives —hopefully with Steemit being a beneficiary.
I was recently talking to my wife about Facebook and expressed my concerns and why I rarely use it. She totally gets my points, but doesn’t want to leave because her friends and family are already on Facebook. So until a viable alternative comes that the mainstream can adopt, I think Facebook is the king for the foreseeable future.
