I vote yes but I will miss a couple of the really big ones.
But there is a way to put a word e.g. iMutual in and that links to a full description. That to me is the best sig because I could put in several sites like abc and def and ghi etc but only take up a line.
No idea how this is done as I am useless at that sort of thing.
