I am wondering what problem Workplace by Facebook is trying to solve, and if they are aware of how 99% of corporations operate? While I acknowledge that SV has for a longtime marketed a Utopian vision of how the post-modern corporation would operate, it was my understanding that this was in fact just a recruiting tool, and not a genuine expectation of how workers need to be supervised and handled. Unless they expect the system to be restricted to just Stanford grads, it is asking for trouble. "Email alternatives" are helpful in that they improve information governance capabilities and security. However, introducing a "social" element to company announcements, policy postings, etc., is immensely myopic.
What is particularly frustrating is that IT groups seem to think that HR has not added social elements to the workplace due to technical ineptitude -- rather than by deliberate design to avoid unnecessary and unproductive distractions.
