Pro TikTok take. It's easier and friendlier to consume. The algorithm is good at tailoring interests. But, it's more like TV than FB.
Con. The algorithm seems to dish out similarly structured videos for all users. For example, it generally includes music that is extremely annoying. (That "No no no" song that is on every other video). At the same time, I also recognize how addictive the app is and because of it I would never download it myself.
Oh, every generation of internet users has made repetitive memes like this; we just have more bandwidth now.
