I thought that too assumed my blog fit the criteria. I was wrong; weighed in at just over 100KB too heavy to get in the club.
My guess is the photos.
I ran a pretty lightweight blog, but sometimes several .jpg would easily cost >512KB
maybe lower the resolution?
at least to test your guess
Exactly, so it's not so much a demonstration of how nice a website fits in 512K as it's about _just not using any media_. Not very interesting imho.
