Hello! If you are looking for approval from the English-speaking masses, I'll weigh in as well. The first two are great. The third however shows a small grammatical error. It should be "Nobody's interested in that kind of thing anymore."

Hi! The first two sentences are natural and absolutely fine for you to say. The third one has a small grammar mistake: 'that' is singular and 'things' are plural, so they don't match. You could either say: Nobody's interested in that kind of thing anymore or Nobody's interested in those kind of things anymore Hope that helps!

The top two are fine, but the last one has a grammatical mistake. It should have been = Nobody's interested in that kind of thing anymore Hope this helps :)
