Poom, I read your post about interaction. It is well structured and you talked about all of the points that a beginner should know before starting any programming course. I liked the video source you selected and you explained the video briefly as well.
The only suggestion I will give is, that you should explain a little bit more about what actions students should take because it is very easy for a student to get distracted by a number of resources available online. Also, you could have mentioned how they can use the learning from this video for the assessment that your Pod has designed after students are done viewing this video.
Good job on your final blog post!
