Internet Explorer 8 will feature a user-generated list of "compatible" web sites, after trials found many ordinary surfers and major web sites can't work with Microsoft's next browser.
The browser's planned list will be targeted at users that Microsoft considers not "web savvy". By opting to use the list with IE 8, they'll potentially be able to view their favorite sites and visit major destinations such as the BBC or Facebook without IE 8 scrambling them.
