Inspired by the success of my
for, I created the

DFR bookmarklet
(Delete From ReadLater, but since these bookmarklets go into
my toolbar, I want to keep their names short).

When you have finished reading an article filed with this tag, just click on
the bookmarklet and it will get automatically removed from your read_later
category.  Note that you don’t need to make any modification to this
bookmarklet since it will use the cookie stored by to authenticate
you (it might ask you for your password the first time you invoke it), so you
can just drag it onto your toolbar and you’re ready to go.

A potential improvement would be to add a JavaScript redirect at the end
since right now, it will simply display the XML success packet, but I’ll leave
this as an exercise for the reader.
