I was very resistant to signing up for TikTok because I didn't think I'd enjoy using the app in public with my sound muted. However, while home one evening a few days ago I decided to give it a shot and was completely astounded at just how fast the For You Page was able to adjust to videos I found entertaining and enjoyable. I think it boils down to a few factors, but the main one is simply that it's able to get a ton of interaction data in a very short amount of time. It's basically all the same data points as from YouTube, but nearly thirty times faster. While a YouTube video is typically eight or so minutes, a TikTok video might only be about 15 seconds. And since your entire screen is dedicated to a single video, TikTok is able to make very specific inferences that something like Twitter isn't able to. So after just a few minutes of swiping through videos, liking a few to indicate I wanted to see similar content, and following a few creators, I was able to get a FYP that felt specifically catered to my interests. Over the past few days, it's even changed dramatically, while still feeling personalized to me, whereas I find YouTube takes days, if not weeks of watching to accommodate to a new interest or topic.<p>All that being said, it's certainly not without its frustrations. For example, there's certain topics I'm interested in that I can't seem to get it to show me videos from (mainly technology topics). I even went as far as searching specific hashtags in the hopes that was enough of a signal, but the FYP still didn't seem to suggest any videos from those topics. It may just be that tech-related videos don't do very well on the platform, and thus the algorithm is unable to collect and process enough data to make useful recommendations.<p>Finally, I absolutely despise the fact that the Following page isn't chronological. I follow a few creators, and I want to see their new content, so you'd think Following would be the place to do that. Well as of right now, the first video on my Following page is from July 11, despite the fact that specific creator has posted six newer videos since then.
