Social media - networks like Facebook and LinkedIn and communication services like Twitter- are more popular every day.
But the next big thing in the social space is unlikely to be yet another network or gadget; instead it'll be developments that make the entire web social.
You won't have to click to a specific website like Myspace.com or LinkedIn.com to have all the benefits of your profile, contacts and network. It'll all follow you everywhere you go online.
Facebook is one social network already doing this through "Facebook Connect." The service allows you to share links, articles or photos with your friends from the 15,000 websites, devices and applications partnered with the company. If you're reading an article on nytimes.com you can click to add it to your Facebook page or share with a group of friends, all without navigating away from the newspaper website.
But the most notable way social will become mainstream is through a web giant like Google . Google's VP of Product Management Bradley Horowitz points out that the web and Google search are inherently social: the more popular search results are posted higher up.
