Hi, I never used LinkedIn, and I will never sign up, because I simply don't need to I have already a job. However, I am curious what do you folks think about LinkedIn? In addition, me and a couple of folks talked about a next generation "Professionals social network" that may replace LinkedIn completely on the Internet, we've been speculating a lot, so I wanted to ask you folks: What features and functions would you like such site to provide? What issues can it solve that LinkedIn cannot solve? Or has not addressed and solved as of yet? Thanks! Feel free to comment, I'd be happy to read! Thanks a lot in advance.
