NONTRADITIONAL - Second Life used for virtual recruiting by State of Missouri

I've had this bookmarked for a while and decided to go ahead and post it.
It is a nice overview about the State of Missouri using Second Life to recruit IT professionals. What are your thoughts on virtual job fairs? I'm somewhat mixed, it really depends on the industry. As far as Second Life goes, I wonder where it falls when it comes to it's current growth and how other online networks compare.
