If someone wants to create a todo list, notes, a text for himself or more, it fits as a text paste. But text Pastes will be way better readable if they were rendered in remarkup. A workaround can be to create a phriction document, but it is often unrelated to the other documents. Also the edit History is hidden in a menu, you can't embed them and you can't add comments.

Maybe the best Solution is to add a Rendered Remakup Language option to Pastes wich will render the text as remarkup. including in embedded previews.
