One major reason was that what we wanted to discover was shifting – from sites we might check out to content that addressed our specific needs.
Instead of using the site as the discrete unit of discovery, it used the page – a specific unit of content. (Its core algorithm, after all, was called PageRank – yes, named after co-founder Larry Page, but the entendre stuck because it was apt).
But once again, what we want to pay attention to is changing. Sure, we still want to find good sites (Yahoo’s original differentiation), and we want to find just the right content (Google’s original differentiation). But now we also want to find out “What’s Happening” and “Who’s Doing What”, as well as “Who Might I Connect With” in any number of ways.*
