The core question a portal needs to answer for a user is How do I find the information I need?
In the early days of the web, the answer was browsing, which made sense when there were a limited number of useful sites. (Remember when it was a big deal for Yahoo to put the New! or Recommended icon next to a websites name in their directory?) But as the number of websites became infinite, search replaced browsing as the dominant paradigm for finding new sites, and Yahoos failure to keep up in this area allowed Google to take the lead.
Facebook has a new answer to the portal question. The social graph, or your network of relationships, will push information to you. Youll learn from your friends. Thanks to Facebooks new developer platform, the types of information being disseminated now include not just news, photos, events, and groups but also music, videos, books, movies, causes, political campaigns and the list is rapidly growing into almost every conceivable category.
