Perhaps we need an alternative to “died”. Digg is still alive. The Yellow Pages is still a profitable business. And yet their cultural impact has been nullified.
Digg isn't really "still alive". That's like saying Michael Jordan is still alive because there's a guy named Michael Jordan. The current iteration of Digg (which is great, btw) has nothing in common with the original other than the domain name.
It would, however, be extremely funny if they took advantage of Reddit’s current travails, dug out the Digg v3 code (not sure if the same entity that owns Digg.com actually owns it) and rose from the ashes.
Or more realistically, just stood up a Lenny instance.
I haven't looked at Digg in a long time. Looking at it now, wow it's terrible, nothing but SEO/clickbait/sponsored trash. I'm comfortable with saying Digg is dead.
