How LinkedIn makes money

So that you don't have to read the article to answer the question of how they make money:<p>1) Ads<p>2) Premium subscriptions<p>3) Selling content to companies on prospective employees

I'm not too surprised. For all the flash and glam behind Facebook, I find LinkedIn more valuable.

"“Scrabulous is not work, and it does not enable you to be an effective professional,” he said."<p>That made me laugh -- very true, and why Fbook will have time selling the same demographic that LinkedIn is monetizing.

I think their attempt at having "company groups" will be a "Facebook Beacon" like success, people will naturally be repulsed from using linkedin.<p>Personally, if they are making money off my personal data, then at least don't charge for the premium account.
