It also doesn't work that well in most technology companies. You will lose your customers pretty quickly if your site doesn't work as excepted or continues to break. It works for sites like Facebook and Google because they have millions of users and momentum that is so great, they could have 404s for 90% of their services for weeks and millions would still come back. They can also segment out a small section of users (which could be in the thousands) to test new and broken technology with almost no repercussions.
