That Facebook one where, having realised the errors of their errant ways, they confess to us all and demonstrate how they've made everything all better.
So sincere.
I think Zuckerberg should be made to perform the same penance as Henry II for the murder of Beckett.
The king performed a public act of penance on 12 July 1174 at Canterbury, when he publicly confessed his sins, and then allowed each bishop present, including Foliot, to give him five blows from a rod, then each of the 80 monks of Canterbury Cathedral gave the king three blows.
All for a bit of medieaval restitution, me.
