What is missing in the site is how to present this info. Right now IE death features are not rendered neither are they searchable merely appearing on the classname for each article element for a feature. Should it be output somewhere? Or just merely be permalinkable (e.g. we can do /#gteie8 and then retrieve list of features that would work when IE8 is dead.
