Facebook's this update will now allow the users to rank and promote the comments — TechGraph
Facebook has rolled out an update where it will rank comments to promote those that are relevant to users. Justine Shen, Product Manager at Facebook said We will continue to take other signals into account so we do not prominently show low-quality comments, even if they are from the person who made the original post or their friends. The users can moderate the comments on their post by hiding, deleting or engaging with comments.
