I'm afraid this comment is more than a little off-topic: maybe not for the thread as a whole, but certainly as a reply to the top comment. It doesn't relate to what rickhanlonii said in any way—and what rickhanlonii touched on is crucial: the kind of discussions we want to encourage in Show HN threads.
Glad to see this. Show HN has always been my favorite part of Hacker News. Anything that can inspire more creation and help product builders find an audience, is a good thing, imo.
I only recently joined Product Hunt, but to me the major differentiator is that Show HN are self-submitted products, while Product Hunt is a curated list. That means I'm more likely to find higher quality and interesting products on Product Hunt, but I'll be the first to learn about a new product from Show HN.
