That was a surprisingly insightful article - I mean we've all heard horror stories of people getting the sack for things they've put on Facebook.

Personally I just don't use Facebook to publish anything anymore, as I foolishly accepted invitations from work colleagues at some point, and now there is no untwining work acquaintances and personal acquaintances.

That said, there seems to be a massive opportunity for someone to create a more business-oriented Facebook. Applications could include recruitment (we all know that "I know someone that's really good" is the best way of finding a new colleague), mentoring, general work-related forums, networking opportunities, advertising to interested others etc etc etc.

Something like that would have real value in the business world, but I'm not entirely sure how you'd go about monetising it without turning everyone off it. Ads maybe??? They'd at least be well targeted for getting corporate dollars
