Dody, it's nice to see you again. But I have to say that a good bit of your post made no sense to me. I did find a clue as to what a "guardianista" is, and to my dismay, what I suspected turned out to be true.

I had not heard of this publication--is it a magazine?--before joining this board. And indeed, when my beloved shanks wrote of the Grauniad, I thought it was an odd name, but took him at his word.
I still have no idea what 'the new black' means.
