Web 2.0 Tools

Web 2.0 is a term used to describe the ways in which the internet has become more interactive and social since the 21st century (the term was first coined in 1999). The activities you do on Facebook: 'liking' things, sharing them, and creating social networks (and being added to other people's social networks) are all part of Web 2.0. So are Twitter and Tumblr.
