Okay, so I've pinched this from DruidX. I've been meaning to do it for ages but am finally getting round to it!
I'll just quote:-
"Okay, so this is Andy's idea. Those of you who don't think you are read, who never get commented or trackbacked, who feel all alone in the world of blog, track back this entry and encourage others to do so as well, and maybe we can make a trackback chain to all the forgotten and uncommented blogs out there."
So go on already!
