Firefox has an AddOn called Reader.
This extension allows viewers to remove all the "crap" from a website and only read the substantial content of a website. For example, the columns on the right, the header and footer, advertising will all be dropped by the AddOn.
The concept should be implemented in our service where we can click a link somewhere to see how such a aread (and certainly a Search Engine) would see the page: plain an simple title / text.
This should help themers dramatically improve on using the correct tags to define the user's content. Also at some point we certain want to look into having some form of basic theme that can be re-arranged just by changing the CSS and not the HTML code. That special Core theme should thus work perfectly with many different systems including the Firefox Reader extension.
