There is an older habit, easily underrated, of being slightly slower to share. The remark that is held back for a day. The photograph that is not posted at the time. The opinion that is offered only to the people present rather than to the audience that could be reached. Each, individually, is small. Together, they were, for the people who maintained them, a quiet form of editing.
The habit fell out of common use, in part, because the systems that benefit from sharing made it easy and rewarding to share. The friction was removed; the audience was always present; the immediate gratification of a response was always available. The pause came to feel old-fashioned, or possibly evasive.
It has, for a particular kind of considered person, come quietly back. The reasons are not nostalgic. They are practical. The remark made in the moment, the photograph posted at the time, the opinion offered to the larger audience, becomes part of the durable public record in ways the older share did not. Each is, in effect, a piece of writing for an indeterminate future audience.
The discipline involved is modest. It is not a withdrawal; it is not a refusal to participate in modern life. It is an additional second of consideration, applied to the share that would otherwise have been automatic. The second produces, on average, a slightly more deliberate share, or sometimes none.
The cumulative effect is meaningful. A person who has been slightly slower to share, over many years, has produced a public record that is, on average, more carefully considered than one of comparable life lived faster. The picture that results is closer to the picture the principal would have chosen, had they been asked, at the time, what they would have it be.
