Google got caught with its hand in the cookie jar now that it seems that it was tracking Safari users even with their privacy settings turned on. Not wanting to feel left out, the Internet Explorer team helpfully point out that Google had not properly implemented P3P on their sites. This initiated a lot of furious wikipedia-ing as people suddenly needed to work out what P3P actually was for the first time in its 15 year life.
Suffice to say, what started as an interesting point regarding how Google engineered a solution to one browsers’ privacy settings as if it was a bug turned into an opportunity for the usual suspects to take pot shots at a rival company.
