Public = private?

It's funny how Facebook is being used for business. I get messages from people I don't really know personally, inviting me to register for their websites or come to their events, and their picture is of them half-naked with their girlfriend at a beach party. Hardly the old world of pin-stripes and formal business presentations, is it? Meanwhile, corporate blogging is making business more human and blurring the personal and the professional even further. On the one hand, I'm glad to see the back of all the false pretensions of old-fashioned business: it's nice to hear people telling the truth for a change. But on the other hand, what are we losing by blurring the boundaries between public and private? What's good for business may be bad for us as individuals. Are we losing ourselves in our work, or just becoming more ourselves in every area of our lives?
