the biggest problem with editor retention at the
moment is the
second edit.
True. The ratio of new users over the past month with one or two edits
to those with three or more would make a great new metric. I hope it
shows up on the report card.
Thanks to Jonathan Morgan for investigating adding new users with
fewer than ten edits who've used the "<ref" tag to the Teahouse
invitation list. I am sure that will be well worth the effort.
