I disagree about the socializing part, in part because so much of our socializing is driven through the same mechanism we might otherwise do work at. Perhaps Justin might have two desks, one that is the communication/socializing desk and one that is the execution/work desk.
Of course a number of people would love to do that where the TV ends up the display for your socializing function.
I think it is good to clearly separate working and socializing activities. Working in an open work space where anyone can socialize with you at any time can be very distracting for work that requires you to focus. In my opinion having a private office and separate watercooler/coffee/socializing space would be ideal.
That said, having that separate desk to indicate that you're working on something that is not so susceptible to distraction might be enough.
