Advantage:
It allows users to create and edit documents online while collaborating in real-time with other users. It can also used for spreadsheets and presentations. The advantages of this is that people can collaborate and edit your work in real-time. Maybe even whilst you're doing it.
Disadvantage:
Expected cons are outlined as the risk that the original authors could not exploit the entire potential of the data they obtained, possible failures in patients' privacy protection, technical barriers such as the lack of standard formats, and possible data misinterpretation. In some forms, this could be online bullying. If someone was to get hold of something private you may have wrote and shared it online, once it's out there, it's very hard to get off. Another disadvantage is that anyone can use it whether it is for their own purposes or for using it against someone.
