It does seem like a rather redundant article. I actually enjoy linkedin, although it does have some quality control issues these days, its still one of my favorite tools for having jobs presented to me, rather than searching for them myself. I think part of what makes all of this work is that linkedin monetizes user data just like the other major social media sites, but is much more in the business of selling that data directly to companies, mostly recruiting firms I imagine, rather than to advertisers who are just trying to peddle commercial goods to consumers. If you use linkedin in a manner where your goals and linkedin's goals align, it works great. I use it to get leads on making money, and linkedin uses my desire to make money, to make their own money. Its not perfect, but its win/win for now.
