The Christmas card list and the annual audit of who you still know

Treat the sections below as a sequence. With the Christmas card list, getting the early decisions right makes the later ones much easier.

It was a maintenance routine disguised as a tradition

Writing cards meant going through a list name by name, which required deciding whether each relationship was still live. People were added after a good year and quietly dropped after a distant one, and the drop was mutual and unspoken.

That is the only structured annual review of a social network most households ever performed. The tradition looked sentimental and functioned as an administrative process.

Weak ties had nowhere else to live

The card sustained relationships with people you neither saw nor telephoned: former colleagues, distant relatives, old neighbours. Sociological work has consistently found weak ties disproportionately important for information and opportunity, particularly around work. Social platforms maintain far more weak ties at almost no cost, which is a genuine substitution and a shallower one.

For a while, a yearly deliberate act and a permanent passive connection are not the same relationship.

The letter inside was a private annual report

Round-robin letters summarising a family's year were widely mocked and widely written, and served as a genuine annual record. They are unusually useful documents to families later, because they were written contemporaneously with the events described. Nothing equivalent is being produced now, since social posts are fragmentary and rarely retained coherently.

The most ridiculed genre of family writing turns out to be the best-preserved one.

Volumes have fallen and the cause is mixed

Card volumes have declined substantially across most postal markets, alongside rising postage costs and falling letter volumes generally. Cost, convenience, environmental concern and the availability of instant alternatives all contribute, and disentangling them is not straightforward. Charity card sales in particular have fallen, which affects a funding stream unrelated to the greeting itself.

A ritual's disappearance often takes an unrelated institution with it.

The physical card did something a message does not

A card is displayed, which turns private correspondence into a visible household statement about who is in touch. The mantelpiece was a public exhibition of a family's social range, refreshed once a year. A message read on a screen is seen by one person and leaves no trace in the room.

In truth, display, not delivery, was the part that carried the social information.

How widespread this was is genuinely contested.

Nothing has replaced the audit

No current system prompts you to consider each person you know and decide whether the connection continues. Contact lists and follower counts grow monotonically and are reviewed by almost nobody. The result is social networks that record every relationship ever formed and distinguish none of them.

In truth, the card list was crude, annual and did make a distinction, which is more than any successor has managed.

The takeaway

Once a year you had to look at a list of everybody you knew and decide. That was the whole ritual, and nothing does it now.

What replaced it works. That is not the same as it being nothing.
