In my post What shape is the internet (September 2010), I said that shifting the emphasis from URL hotlinks to search undermines the idea of the internet's being web-shaped. This point is also made in a post by @apike, referenced by David and also called Burying the URL (April 2014).
URLs are the essence. They make hypertext hyper. The term “web” is no accident – it refers to this explicitly.See also an excellent Twitter debate following @apike's tweet.
When David talks about bifurcation, he means that "enterprise IT is diverging enterprise technology from consumer technology in a way that’s creating two irreconcilable branches of technology". He observes that most company intranets have a pretty lousy search facility.
But most company intranets have pretty lousy cross-linking as well. They are mostly just pdf graveyards stuffed with documents of indeterminate pedigree, which people are often reluctant to waste time searching (even if the search facility were better) because they don't expect to find anything of value.
Actually, you can't always find what you are looking for on the Internet either, and that has a lot to do with the limitations of search, but there are enough amusing distractions to conceal this fact. Surely we don't want our company intranets to copy the internet too closely?
And remember that the data revealing Enron's problems were cheerfully displayed on the Enron website. But nobody important had bothered to look at these documents properly. (Actually, a bunch of students had analysed them years previously and concluded that Enron was bankrupt. They probably got low marks for that assignment!)
There is an increasingly common belief that the technology used inside companies should work the same way as outside, should provide the same "affordance". This is not Bring Your Own Device but Bring Your Own
