Ah. Thank you. You made me realise something. The difference is, text messaging and email allow you to communicate linguistically with people within your social network in a peer-to-peer (one-to-one) fashion -- whereas a social network platform allows you to define contacts and their relation to you and use a befriend/unfriend, follow/unfollow model where once befriended or followed you automatically get delivered (in theory, unless muted or an algo decides otherwise) broadcast (one-to-many) messages Did I get it right? I think so? Devil's in the details...
