I'm far from a web design expert, but I've made a point to try and leave as small of a footprint on my websites as is practical.
It's better for me, as I don't have to monitor as much junk. Don't have to worry about hitting all the right analytics.
It's better for visitors, as you all get faster page loads with fewer hassles.
It's better for the planet as I can do a lot more with fewer resources.
