my connection bandwidth probably does not do it justice, pages load at the same speed, but begin loading instantly, as opposed to a 1 to half second delay,
for some small tweaks to get even faster page loads, i notice those share images down the bottom are 32x32 images re-sized down to 29x29, you could cut some size away by cropping them down, though its not much, a larger contributor is the laughing gif, its 30KB by far the largest image on the page,
I've attached a shrunken copy of your avatar pic, for reference to show they can be shrunken, and i only went lightly on the averaging ,
