There has been much talk in the media about Web 2.0, but what exactly does term that mean? At the opening session of the ERE Expo 2007, this topic was discussed in great detail. Basically, 2.0 is a continuation of 1.0--or the beginnings of Internet functionality. Web 2.0 is all about the user becoming immersed in social network marketing, with sites like MySpace, You Tube, and Digg becoming more and more popular. It's also about the way we communicate now, rather than just by email, but more commonly by blogs, comments on blogs and IM?s. This is the first time in history that job seekers have been given all these tools to find potential employers, learn about interesting companies, and even network with possible hiring managers through video resumes, profiles and instant messages. How have these tools helped you in your job search? And what does Web 2.0 mean to you?
