Web 2.0

Web 2.0 refers to the second generation of web development and design. This includes communication, information sharing, and collaboration on the web. Web 2.0 has led to the development of other web based communities such as applications, social-networking, hosted services, wikis, folksonomies, video-sharing sites, and blogs. 

Pros: Web 2.0 can be beneficial because it simplifies the communication process, which makes everyone be able to communicate and stay in contact with everyone. Web 2.0 also offers the development to post pictures and videos for other people to see. Business can also have people come onto their site more and receive better feedback because of customer referrals. Lastly, there have been applications that are easier for people to work with which are affordable. 

Cons: On many websites, information could be leaked out. Social network becomes more important and you don't focus more on your work life or even your private life, because your whole life is streamed out onto the internet. Also, there are many security threats that are a risk on the internet today.
