I liked that the lectures were fast and delivered in a fast pace. It was good because it didn't get boring and didn't feel sluggish! It's good for those who want to implement word clouds in Korean in a short period of time! However, the image quality wasn't that good, so I had to zoom in on the code part every time to listen... (I know there's code on the blog, but I'm the type of person who studies by following the lecture and writing code...)
