Efeito expandir área de postagens do blog

DEMO

Este efeito já é conhecido em alguns sites como Facebook e Twitter. A medida em que você rola a página principal do blog, novas postagens vão se abrindo, assim é possível que seu visitante navega por todo o seu blog sem sair da página de entrada. Que tal então usa-la em seu blog ? (mas atenção, se você usar menu de navegação em seu blog, este hack não funcionará.

Vá até o modelo de seu blog e clique em Editar HTML

Procure por <b:skin>...</b:skin> que está logo acima no código.

Abaixo dele, cole o próximo código, e depois é só salvar: (se quiser trocar a imagem do loading(imagem que aparece ao abrir a página, troque o código na cor vermelha)
