I agree but an alternative is what "reader plus" gives you, an option to mark all items above or below the current item as read. You can do that as the default by turning on the "scrolling marks as read" and "selecting does a scroll" but it's not necessarily something you'd want to have on by default. It does save a lot of time though for feeds with lots of posts where you tend to only read a small portion of them.
