I know this person!! Is he from SK Planet? We've worked together a few times and he's really sincere and hardworking. Who would've thought I'd see him here!! I don't usually leave comments, but this is an overwhelmingly helpful video!! I'm a marketer, and I organized the report the way you gave me and it's so great.. You organized difficult technical terms all at once, and you even made it possible to download the valuable website summary on one page, so I got a great deal. ㅠㅠ Thank you so much. I'm not a traditional marketer, so I was struggling with the concepts, but this was a lecture that helped me understand the overall flow and trends~~ I'm learning a lot from watching the video! But he speaks a little slowly, so I'm watching it at 1.5x speed ㅋㅋㅋ ^^ Thank you~
