a list should not be a hack
My "iTunes, Therefore I Am" sidebar is based on a category dedicated to it, that accepts trackbacks. That is ridiculous.
Lists are so common that we need a simple way to make them. A list is different than an entry. Lists need to be their own thing.
A list needs entries that consist of a single item. To make things simple, we could leave the item up to the user, so if it was a link, it could be a link. If it was simply text, it could be simply text.
