Wikipedia editors are people, and that means that they have the same problems that other people have.

In the 20+ years that Wikipedia has been around, 47,318,167 accounts have been registered, but only 123,717 have made an edit during the last month, or about 750,000 during the last year. Among them, we probably have something on the order of:
