Which elements of Web 2.0 suits your needs as a student?

A blog and a wiki are the most important for my needs as a student. This is because they provide the information I might need to complete a project.​ 

Wikipedia - Largest wiki on the internet with shared opinions
on almost anything

I need the wiki because it gives a very good starting point on a project and then links you to other sources so that you can inquire more, plus, it also has the shared opinion of everyone so you have a broader viewpoint.

I need the blog because it allows me to share and find videos, photos, and other sorts of media which i can use in my presentations. Another reason is that it allows me to find out what other people think about a subject and merge it into my own view.
