Milestone birthdays
A 30th, 40th, 50th or 60th usually means a room with decades of a person's life in it at once: university friends next to colleagues, siblings next to people the guest of honour has known since school. A shared wall gives everyone one place to add to, rather than the photographs staying scattered across whoever happened to take them. For a milestone, the album afterwards ends up being a fuller record of who actually came than the photographs any one guest took alone.
