Interview Prompt
We measure each content format by how many items registered account holders have published, so an item whose creator has no matching user record does not add to a format's total. Take the format sitting second by that total (include every format tied for second) and return the complete records of all its items, whoever the creator is.
Summary
The spotlight finds number one. The story is in what comes right after.
