Facebook said Tuesday, Sept. 17, 2019, that it expects to name the first members of a new quasi-independent oversight board by year-end. The oversight panel, which the social network first discussed publicly last November, will rule on thorny content issues, such as when Facebook or Instagram posts constitute hate speech.
