Deletion of Blinkenlights

Comment: It's origin is a joke poster written in faux German.  But its usage to refer to diagnotic LED lights on computers and telecommuncations equipment persists.  http://books.google.com/books?id=kOQ9m38q_t8C&pg=PA78&dq=Blinkenlights&hl=en&ei=c7S1TNXdJsrVngfXxblq&sa=X&oi=book_result&ct=result&resnum=1&ved=0CCgQ6AEwAA#v=onepage&q=Blinkenlights&f=falseThis book documents it with a writeup of over 1 page which goes beyond a passing mention.  There's http://books.google.com/books?id=a2Q6U0b36rMC&pg=PA14&dq=Blinkenlights&hl=en&ei=c7S1TNXdJsrVngfXxblq&sa=X&oi=book_result&ct=result&resnum=2&ved=0CC0Q6AEwAQ#v=onepage&q=Blinkenlights&f=false code snippets in progamming books describing how to program your own Blinkenlights.  There's http://books.google.com/books?id=Q5OHEW8_gysC&pg=PA155&dq=Blinkenlights&hl=en&ei=c7S1TNXdJsrVngfXxblq&sa=X&oi=book_result&ct=result&resnum=8&ved=0CE4Q6AEwBw#v=onepage&q=Blinkenlights&f=false other writeups too.  This a weak keep for me because it borders on a |dictionary definition for a slang term for LED diagnostic and status lights
Stance: keep
