I didn't dig around much to see if it has anything in the way of content filtering, but I loaded it up at work and was greeted with a page filled with scantily-clad ladies in suggestive poses. I work information security so I spend a decent amount of time evaluating risks associated with allowing certain sites at work and visiting random websites is not frowned upon for this reason, but as soon as I see suggestive materials I'm out of there.

Hey Microsoft, how about some content filtering turned on by default to hide potentially objectionable or NSFW materials? Also while I have your attention, why roll this out without any WP8 integration?
