content: Meh, Linkedin is a cesspool anyways, It's all the obnoxiousness of facebook with a thin veneer of business ego. in my entire professional circle, I know of no one who's ever hired, shopped for or interviewed someone based on their profile there.  I think all MS want's is more user data to mine - at least this is a slightly focused attempt at capturing professionals. I'm sure the userbase of linkedin generally has a higher level of disposable income.
