The last couple of days there have been duplicate entries in https://bit.ly/blinkintents but not constantly.

Assuming no deletions we have the 8 most recent entries:

9/28/2018	Demetrios Tsillas		rectly monitor the addition of HTMLElements to a Document

10/3/2018	Mathias Bynens	Ship	well-formed JSON.stringify

That is 3 that have been duplicated and 2 that have not. 

jochen checked for a duplicate running script and didn't see one, so it could be some hiccups in the editing APIs/error handling. Or something else. Slightly interesting that for the first 2 duplicates, they didn't come immediately after the correct/original line. There is also one entry with a truncated line which may or may not be related.
