I haven't done Facebook since 'planking' was a thing. Just don't see the point of posting everything about my life. It could only hurt me in the future. However, if I owned a business I'd probably use all social media for business purposes.
And while I never really liked Zuckerberg, I have been impressed with his recent stand for free speech, that had earned him nothing but scorn and hate from the Left. Hope he had the will to keep it up!
