I wrote an application which filters articles on hacker news and gets rid of lead capture forms, sites with pop-up advertising, paywalls, etc. Also articles about iPhones, MacBooks, Rust, Equifax, CCleaner, etc.
The problem is that it has an "irrelevance model" that cuts away really savagely at topics which have many articles that I don't care about. These topics include Apple, Bitcoin, etc. Probably many other people feel the same way about most of those topics, but there is one topic on my list which is what they live for.
I can probably get it working for somebody else if you are interested. Click on my profile link and I can demo it for you.
