It's plain silly when the sig is longer than the post it's attached to. Shows more interest in advertizing the self than in responding to the thread.
Besides, does anyone bother to read a sig when it's simply a list of gear? I know I don't. Personally I'd rather read a dissenting political opinion than a shopping list.
I used to drive a Heisenberg, but whenever I'd glance at the speedometer, I'd get lost.
