YouTube problems with Safari for many users
It seems that quite a few other users are having problems with Safari and YouTube after the recent updates.
(On another note, there's even more problems with Facebook and Safari.)
It seems that Safari isn't getting along with the web's two most popular sites. I am having these problems myself. Chrome seems to handle them fine, being WebKit also...
