It's slow because it's text based. I think there could be advantages to switching to compiled html or any other open binary page format. It would be less flexible, but at least it would be less abused: no more pages and pages of CSS, weird js widgets, blurbs of html. Compressing html with gzip is not that much efficient either. I don't think it's a great idea, but in some case it would sort of force everyone to make content that is just lighter.
