Does that "Are you on?" advertising from eon annoy you too? I find it just completely ridiculous. And they have no idea about web design either – on Chimera (a Mozilla-based OS X browser) you just see an empty red page.
I mean, sure, some web designers assume certain browser features, but we're talking about a damn advertising campaign here! Who's dumb enough to set up an advertising campaign so that someone gets absolutely no information just because they suppress advertising popups on the web? You can't be that stupid...
