For example, suppose someone doesn't want to read about AI. Instead of blanket banning words or having custom ublock origin scripts (which is what people are doing nowadays), it could ironically use AI (jev) to do that perhaps more robustly.

I think that this is an interesting idea though.

In theory, I would also like to see something which can get the gist of my account (and then find out all the things that I like for example) which could then give the keywords for the curation. This way I wouldn't have to enter the amount of keywords as well.

Really interesting and meta project for hackernews, starred :-D
