As much as I understand you, SG, but signatures are just as important as your avatar. Your avatar shows everyone part of your personality, some little thing about you. Some have stupid pictures of laser-spitting smileys, others are more serious. But everyone can display the world a bit of themselves. Signatures do exactly the same, just that you can show a little bit more, make you a bit more you, make you more unique. Think of it like that, without signatures and avatars all your account would consist of would be your name and the text you write. Sure, you can argue like "it's not really necessary", but then you can go and remove avatars as well. Why, you say you wouldn't? Then ask yourself why. The answer is the same why signatures are a good idea. I think you exaggerate a bit saying they're useless and distracting, because, in fact, they are not. The reason why they are not is, that there are rules which must be obeyed. Options for users can be added like "disable signatures", so you wouldn't even see the text you seem hate so much. It depends on the user himself whether he likes to see the signature or not. And after all they are only pictures, no annoying flashing movies.
