If I was a betting man, I'd bet their daily visitors have shrunk a fair bit the past few months. Who is the type of people who would even visit daily to discover random products that share no theme? Most of them probably are just checking for competitors or journalists looking for a story. Not real actual users. This their downfall.
I don't think this is true at all, and I would bet the opposite. They are bringing in live chats/podcasts/etc and going outside of their normal demographics. If anything it is similar how reddit used AMAs (by Obama, etc) to expand the reach of the platform to a wider audience.
