I sincerely doubt this is going to kill LinkedIn. I've actually stopped using Facebook because the signal/noise was all noise. LinkedIn is far more professional and just being able to group my Facebook friends isn't going to do much unless I can make Facebook show different profiles to different groups of people. But, you know, why bother? LinkedIn works great for professional contacts, can't see any reason to try to embed LinkedIn inside Facebook.

This is not a LinkedIn killer. <p>As an example:<p>Facebook's job search feature is a joke - it's just a section of the "Marketplace" and is filled with the typical "Make money from home" ads. <p>LinkedIn solves legitimate problems business people have with Facebook and other social networking services.
My Boss (Executive VP) is on LinkedIn.<p>His Kid (15 year old daughter) is apparently on Facebook.<p>Sounds to me like it's two different worlds. I highly doubt I'll be seeing my 50-some year old boss on Facebook giving me Vampire bites any time soon.
"Facebook Killer Feature" - means a feature Facebook developed, meanwhile...<p>"LinkedIn Killer Feature" - means a feature that will kill LinkedIn.<p>Confusing. Yet another reason never to use "killer feature" or "_____ killer."
