Does Twitter mean business with LinkedIn deal?

Everyone seems to be talking about how first Facebook and now Twitter are being adopted by business users, as if the concept of social networking in a business environment was somehow new. Of course, the truth is that services such as LinkedIn have been providing just that for many years now. Indeed, LinkedIn has fairly quietly grown to some 51 million members worldwide now, yet still seems to struggle to command the same type of media pulling power that either Twitter or Facebook have when it comes to generating news headlines and publicity. I suspect there will be no such problems today as LinkedIn cleverly announces what it calls an 'integration partnership' with none other than Twitter itself, allowing members to share their status updates between both services.
