Yeah I would like for more suggestions to be more tuned for me and less tuned for advertisers too.
If there were a project that was not monetized but that requested some feedback from you to help make itself better, and whose purpose was to help to quantify and make informed, fulfilling decisions about some things, would that seem worth checking out?
For the problem of quickly making many similar decisions, I agree with Abishek about machine learning: I think it can provide the opportunity to be faster, more rational, and eventually more explainable.
How would you quantify what you're trying to optimize? Do you think you could recognize a satisfactory decision after making it, potentially assigning a happiness number to it, to inform a machine learning model?
My take on this problem is classify it into a couple of categories: 1. recommendations for things you only really need to do once (buy insurance, choose a college to attend, etc), and 2. things you do lots of times (eat breakfast, do chores, etc)
Things that you only do once might merit more thought per instance, whereas things you do repeatedly might be easier to do more quickly due to having had more experience or more data working with them.
For the first problem of having unrelated decisions to make, I don't have much advice other than that if it's possible to classify things in a way to make them slightly more repeated then that could be helpful. For example, buying insurance could be treated as an instance of buying something, and when buying something it could be interesting to know the value of your time to inform how much time to spend choosing.
(I'm encountering a character limit so I'm splitting my response into a few comments)
For the specific case of learning a foreign language, I wonder if it would help to have audio in one language and subtitles in a different language (one familiar language and one less familiar language, and sometimes switch which is which). I believe Netflix supports subtitles in a different language than audio
I, too, would be interested in a way to connect with individuals interested in helping out with a project for a little bit.
I have a free, open-source smartphone app that I've been enjoying for a while, and I think it would be really helpful to get some fresh eyes to help with things like making the store pages and the app itself clearer. I wonder if the specific problem of an app needing clarification is a sufficiently common sub-problem.
Here's mine (which is about motivation and efficiency measurement) if this sounds interesting:
