Too Long; Didn't Read
Twitter recently added a new feature, instead of just a conventional profile photo, it allows users to identify themselves with an NFT picture. NFT (short for the non-fungible token) is a digital commodity, most commonly a picture, whose ownership is documented on a blockchain ledger. The technology that underpins NFTs reminds us of an important aspect of how we live in society. People will spend ever more money expressing themselves online as more of our social lives become digitised.
