James Shelley, in “The Purloined Tweet”:

The person who “benefits” from a Facebook update that says “Hey, I’m drinking a vanilla latte!” is probably the person enjoying the vanilla latte. After all, the only guaranteed reader of a text in social media is the person who wrote it! Such is the curious phenomenon of posting personal notes with no specific benefactor or recipient in mind.

As a closing point of reflection, perhaps in a cautionary tone, consider the old maxim of Cyril Connolly: “Better to write for yourself and have no public, than write for the public and have no self.”
