Irony alert:
Database overload for an article on lightweight websites.
It's a little pedantic, but if you're going to talk about how sites should be lightweight and then use a sizeable PNG image you're sort of opening yourself up for criticism.
I don't expect good design from bloggers. If they say smart things, I'll read. I expect good design from people who theoretically want my money, because it's their job not to irritate me when I'm trying to pay them.
I've avoided buying products from companies who make terrible design decisions. Not even to punish them, just to avoid having to deal with the pre-product bullshit.
