I personally like it because not everyone follows every altcoin - it's WAY easier to read this way (especially now on mobile) instead of a huge page with a wall of text and charts and videos. I feel like people who don't do TA or understand what @haejin is posting just see a couple of images and some text, but for people who do understand, these are full of information. It would be way too much if it was all one post.
Also, like @weirdheadaches said, it's his platform and he can organize the information as he wishes. If people didn't like it or find it useful they wouldn't upvote or read his posts.
