To beknown or not to beknown?

Today I found out that monster has an app called Beknown. I guess it's trying to compete with LinkedIn but it works through Facebook.

"BeKnown makes it easy to build your professional network on Facebook - while keeping your personal and professional lives separate."

BeKnown users on Facebook can now:

Create professional networks within an environment created by Monster without ever leaving Facebook
Easily invite contacts from other social networks to expand their BeKnown network beyond their existing Facebook friends
Keep social activity with friends and family separate from work-related activity with professional contacts
See who among their professional contacts on BeKnown is connected to a company or job opportunity they are interested in
Connect professional networking to Monster’s job search and browse tools and import their Monster profile to BeKnown from right within the app

I think this is a good idea but I'm not sure I'd want my social circle to be so close to my networking/job search. I feel like it's important to keep my facebook life separate from my career. Plus, Monster is like stage 5 clinger status. Once you give them personal information, they never leave you alone!
