You know that radiation, left over from the big bang, that produces the static that you hear when your radio isn't in tune?
That's Shizzo, on this board.
A not particularly loud, but persistent source of static that permeates everywhere.
He isn't terribly difficult to ignore, but there sure is a lot of him

(though being fair, this is what I remember of Shizzo before he went away - I did read a few posts of his today and it seems either his mindset is different or he will not be providing static, as yet)
