I’ve been playing around with a blogger hack that allows short summaries of posts to be displayed on the main blog page: with full posts appearing when you view the main post (they appear “below the fold”.
It seems nicer to me: maybe others disagree. The only bit that irritates me is that you don’t get any indication, from viewing what appears on the main page, whether or not there’s extra content “below the fold”. So you have to write this in yourself.
