There's a potential huge problem with these social media sites, Google (GOOG), Facebook (FB), Twitter (TWTR). You know everybody whose business model is advertising where the user pays nothing, if you want to use Facebook, if you want to use Twitter, it costs nothing! It doesn't cost you anything to have a Twitter account, to have a Facebook account, it's all free!
Well if it's all free how does Facebook make all this money? Well, they make all the money by selling the data that they collect from all of their users to advertisers or political campaigns or anybody who needs personal information in order to market their product or sell their product. That is the trade-off that everybody makes - you get the service for free but you know that they're using your information.
I think the public, potentially there could be a backlash regarding just how much information the social media companies are actually retaining.
