Mine's in the reasonably big category I guess...
Seriously though, some people like to have such sigs. To be honest I have never had any complaints. But yeah, some of us have to make do with less ideal connections and for you/them it's a nuisance sometimes. Luckily it's not as bad compared to what I see on other fora though.
But if you wish, you can always turn off signatures.
Go to your profile, and under "look and layout preferences" check the "don't show users' signatures" box.
This way you can have faster loading times and you don't have to get frustrated by sigs like mine.
