A blog could be used in a lot of different ways. A blog is like a website but with more information. You could put videos, images, music and comments in your blog, which makes it really interesting. You could use a blog to communicate with people and get to know more about them.
My Grade 6 WIKI Web 2.0 is a way to learn about wikis,blogs,podcasts and much more. Its a new way of technology to learn about those things. You can also get music, videos and pictures. I think its a new internet explorer that helps people learn more about it with really good information.
