Adds a just_a_tweet function and short code that allows you to display only
the most recent Tweet from a Twitter feed.
This came about because I wanted a way to display my most recent tweet in the
header of my site. Looking through dozens of Twitter plugins I couldn’t find
one that just got the most recent tweet without too much extraneous HTML and
also cached the request. This function does both.
For more info, visit Nutt.net or
my Twitter feed.
