A week gap will create a discontinuity in the diaries.

I still don't understand why the curators don't just build a database by downloading the for #thediarygame tag from the blockchain. I assume SteemIt Inc has direct access to the data.

I used the infinite scroll feature of SteemIt.com and download what looks like a complete list of entries in the diary game from the page:

https://steemit.com/created/thediarygame

I made a report showing everyone with five or more entries in the game.
