Incognito mode doesn't make their recommendation system any better, but at least it doesn't get stuck on some stupid subject because their bs algorithm deemed it important to show the same stuff several days in a row.
What this does is to tune the recommendations for that session to what you view for that session.
If you blindly follow some pratfalls or kittens video, you'll get served up junk. If you happen to be researching some specific topic (how-tos, explainers, academics, technical topics being among my favourites), you'll tend to find you're getting recommendations that follow from that initial topic.
I still treat recommendations quite warily, but at least the ones that come up in such sessions are somewhat better than standard fare.
