I have sincere doubts that a single short (or even long) prompt is enough to get a working app/game beyond some trivial level of difficulty. And even if it were possible, such a thing would be interesting to only a very small subset of HN readership. I'm quite interested in recent AI developments and I would still not click on such a section.
If it is something the community finds intellectually interesting, then those posts will tend to do well organically.
