Great analysis, but I'm even more surprised to discover that producthunt is a "real" website at all.
I blocked PH with ublacklist a long time ago for looking like SEO promotion/garbage and looking too much like those "VS/comparison/best 5 apps" websites with next to zero content. These pop out faster than what I can filter by hand.
After checking it out again and knowing it is not purely-generated content, I _STILL_ don't see the value proposition if I stumbled on such a result.
I know multiple companies that care quite a bit to get a good listing on PH, but I had exactly the same reaction: Are there end users or companies that actually care?
