I really appreciate that your blog post is very well constructed and edited, your attention to detail is a big step forward in creating multimedia content. Besides your efforts on the structure, I also learned a lot from your practical application of the multi-media learning principles. The signalling principle that you have adopted is obvious throughout your blog by which helped me to focus on the main points to have a deeper understanding of your description. Overall, this blog is entertaining to read and delivered abundant material. I wonder if the size of  text can be enlarged a little bit next time, it will be more convenient to read for poor eyesight guys like me. Keep it up! you are doing a decent job! Link to the post.
