Oh, wow, I have just noticed this blog post. Blogging has made such an impact in my journey with technology and opened up so many virtual classroom doors. Although I started blogging more than 8 years ago, it is more essential than ever, that teachers and students should have an online space for sharing with others, potentially from around the world, to engage them in learning and sharing. It is indeed a necessary 21st century literacy. Thanks Marie for the feedback and great to see that you are going from strength to strength with your blog.
