Two big problems surface pretty much immediately: 1) It takes a lot of time and energy to scan all of these messages, and 2) The person or bot that creates the highest volume of messages will also occupy the most mindshare among your team.
Things tend to look grittier in hindsight. Maybe it’s the patina of age, or the strangeness of a distant era—or the black-and-white rendering—but a strange side effect of old photos is how they lend gravity to even the most innocuous subjects. Aging photographers know this best, often discovering much later that photos made in their formative years have accrued a depth that wasn’t there at inception. This mutability is part of what distinguishes photography, tethered as it is to our predilection for nostalgia. But pictures don’t actually change over time. It’s us, in our romanticizing of an opaque and intangible past, who compartmentalize time into orderly, discrete segments and call it history.
