Cloud gaming is solution looking for a problem. It's not customer demand driven. Nobody want's cloud gaming (at least not yet). They haven't shown anything compelling why this would be a game changer for end users. The games are not more fun or unique than on any other platforms. Any of the cloud arguments also hold for consoles or PCs on internet connected games. I think the site may be a bit optimistic.
Every time someone posts "Nobody wants cloud gaming" half a dozen people come in and say "Actually, I want cloud gaming" Don't mistake the fact that you don't want cloud gaming for nobody wanting cloud gaming
Also don't mistake half a dozen people on a tech forum as being indicative of a mass audience that's commercially sustainable for something.
Especially given HN is rather prone to imagine a product as turning out in a utopian perfect way rather than the more realistic "compromised by the requirement to be economically plausible" one.
