I think there could be a lot of use in having some sort of pop up window block. It would dim the current page you are on and display this block on top of the page.
This could be used for really important announcements, butt I think they could be more useful if they are able to be triggered by a button.
Example: Learn More button - instead of opening a new window. It opens a pop up on top of the page you are on.
This could really help with not having a page for everything, and keeping the flow of the website simpler.
