TikTok has replaced Reddit for me (I can expand more on why I stopped using Reddit, but it's not related to TikTok) in terms of "checking what's up on the internet" or as Reddit would put it "Checking the homepage of the internet".

I trust TikTok's "algorithm" to give me quick and entertaining short-bits about what's going on, what's interesting, etc. It learns what I'm into effortlessly, and I appreciate how every now and then it would throw in a completely new (to me) genera or type of content to check out. Whenever I open it, there is a feed that's been curated to me about things I'm interested in checking out, few new things that are hit or miss (and I like that), and very few infuriating/stupid (to me) things.

Its recommendation engine is the best I have used. It's baffling how shitty YouTube's algorithm is. I discover YouTube channels I'm into form TikTok. Sometimes I'd discover new (or old) interesting videos from YouTube channels I already follow from TikTok first. For example, I follow Veritasium and 3Blue1Brown on YouTube but I certainly haven't watched their full back catalog. YouTube NEVER recommends to me anything from their back catalog. When I'm in the mood, I have to go to their channel, scroll for a while, then try to find a video I'd be interested in from the thumbnail/title. And once I do, YouTube will re-recommend to me all the videos I have already watched from them (which are already their best performing videos). Rarely would it recommend something new from them.

On TikTok, it frequently would pull clips from old Veritasium or 3Blue1Brown videos for me which I'd get hooked after watching 10 seconds, then hob on YouTube to watch the full video. It's insane how bad YouTube recommendation algorithm is. Literally the entire "recommended" section of youtube is stuff I have watched before, or stuff with exactly the same content as things I have watched before.

Here is how I find their recommendation algorithm to work:

YouTube: Oh you watched (and liked) a brisket smoking video? Here is that video again, and 10 other "brisket smoking videos". These are just gonna be stuck on your home page for the next couple of weeks now. You need to click on them one by one and mark "not interested" in which case you're clearly not interested in BBQ or cooking. Here are the last 10 videos you watched, and some MrBeast videos and some random YouTube drama videos.

TikTok: Oh you watched (and liked) a brisket smoking video? How about another BBQ video, a video about smokers and their models, some videos about cookouts and BBQ side dishes, a video about a DIY smoker, another about a DIY backyard project for hosting BBQ cookouts, a video about how smoke flavors food, a video about the history of BBQ in the south, a video about a BBQ joint in your city (or where ever my VPN is connected from), etc. And if you're not interested in any of those particular types, it learns from how long you spend watching the video and would branch more or less in that direction in the future.

Another example is search. Search for "sci fi books recommendations":

YouTube: Here are 3 videos about Sci-Fi books. Here are 4 brisket smoking videos. Here are some lost hikers videos (because you watched a video about a lost hiker 3 weeks ago). Here are 3 videos about a breaking story in the news. Here are 2 videos about sci-fi books, and another 8 about brisket.

TikTok: Here is a feed of videos about Sci-Fi books. And I'll make sure to throw in sci-fi book videos into your curated feed every now and then to see if you're interested.
