One query, not one per account: a list of N accounts that costs N+1 queries

is the kind of thing that is fine with three accounts and unusable with

three thousand. Counts come from left joins so an account with no activity

is listed with zeroes rather than dropped.

`joined_at` is the account row's own creation, not the GitHub account's; it

is when this site first saw them.
