Subject: 23.3; Please use js-mode for JSON
Date: Wed, 20 Apr 2011 23:48:55 +0100

The web page for espresso.el, from which js-mode derives, says that it
can be used for editing JSON. Since Emacs doesn’t currently have a
dedicated JSON mode (and indeed I can’t find one anywhere), perhaps add
an auto-mode-alist for .json to use js-mode, as espresso’s page
suggests?

Sounds reasonable.  I've done so, thanks.
