To be a successful webmaster you need to roll with the trends, regardless of your personal feelings, otherwise your competition will destroy you.
Very true. And whether Facebook is a fad or not, it's still a measurable success (500-600 million active) and may soon become a behemoth in online advertising.
Plus, the number of mobile Facebook users is increasing exponentially and it could serve them (and Microsoft) well to have a trusted, integrated search capability. Most folks I know who stay glued to mobile Facebook find it inconvenient to leave the application, and navigate to the Google or Bing to search the web. If Bing is integrated, the number of eyes peering at Bing SERPs will grow.
