Interesting possibility, but I'm not completely sure this would work. I'm sure that a "jobs" section of facebook would gain plenty of interest, but I think LinkedIn appeals to people who would like to keep their job-related networking completely separate from their social lives. The line between professional and personal life will shift, and this may be a generational thing. But who knows, the distinction may sharpen rather than blur. One of the big reasons I haven't left a huge web/video trail of my own stupidity on the web is that I'm old enough that the web was still an infant when I was in college, and nobody had cell phones with video cameras and recorders. Now, anything even slightly unusual on a college campus will be recorded by at least a half dozen people. You could figure that people will blend social and professional lives as they they get more casual about these artifacts. But maybe they'll just learn to draw very fine and deliberate distinctions - kind of the difference between getting excessively drunk at a work event and getting blotto at a bar where your colleagues just happened to show up later in the evening. Anyway, I went a little off topic there, but maybe there's a long term niche for social/professional networks that are explicity not social/casual.
