This is not for 'deep' or 'slow' reading with intention and focus. The idea is that you have a large pool of incoming stories and you aren't interested in 'reading' all of them, but you want to reduce the chance of missing a single story. You want to 'screen' all stories.

This UI explores a 'mark-and-clear' idiom; you mark a group of stories as 'read' and then you clear that group, purging the stories from your view completely.
