I would like to change my profile, but for some reason the profile page breaks cause I blocked scripts from maps.googleapis.com. Whatever map feature that is, it cannot be so essential to the site that the page should not need to bother with graceful degradation, can it?
Also I know the google recaptcha is a really handy thing, but aside from allowing google to track stackexchange users, recaptcha is also hardly the most secure captcha.
Even the ajax.googleapis.com could be backed by secondary cdns easily.
My point is, it shouldn't be hard to modify the site to allow its use to users who block google scripts. Maybe I am just 'one of those', but in my experience a suprising amount of people seek to avoid google tracking. So wouldn't it be worth the (little) effort?
