True, though I think this thread has done a great job of bringing some of the unmentioned-but-existent apps to light, more so than a few hours of research by the authors. Something of a side-effect, and one of the reasons I click on "comments" for many HN stories.
It doesn't speak very well of the credibility of the investors who wrote the post to say they'll pay for something without any apparent knowledge of existing solutions, nor any critiques of why they're deficient. It's like saying, "someone should invent a good car."
