I know we already have evangelism bugs, but having a mail written to the webmaster is, imho, not enough. The non working site's webmaster needs some facts, so he can get some budget.With that buget he/his team will be able to rewrite the site and adapt it to FF/Mozilla etc ... We have the power to give those webmasters facts and numbers so they can find the money needed to build better site visible from non IE browsers. To be realistic, we need to join forces with other browser maker (i.e.: Opera, Apple, KDE), so the stats of the site will not show that the effort is mozilla based.
So how do we give webmasters the numbers they need ?
By changing the default homepage. I suggest we select a page from one of the evangelism bug. And we could change our target website every couple of month. With all the buzz around security and recommendations to switch to non IE browsers, giving numbers would help.
