For all their power, I think most people's biggest interactions on the web are with Facebook, Youtube, Amazon and Google. Do you have any good examples of VC-funded UX experiences that fairly prevalent?
The OP is not a blog post, but an Ask HN participant. Most of the poeple on this site are building VC-funded UX, and are early-adopters of the same. My comment is addressed to them, not most people.
Additionally, it is beyond my ken to even begin to comment on the bigness of people's interactions with anything, in general.
