Investors were wildly excited ahead of Facebook’s (FB) January 15 announcement, which despite wide spread speculation over a number possibilities -- a smart phone, video service and even a dating service of sorts -- turned our to be for Graph Search. While many were arguably underwhelmed with the announcement, I still think that long-term it’s in the cards for Facebook to launch its own full blown search engine. After all, the promo for the event did read “come and see what we’re building” not what’s we’ve just built. For now the billion plus users will have to be content using Graph Search. That’s good for Google (GOOG) and Microsoft (MSFT) as well as those other search engine companies - IAC/Interactive (IACI) and AOL (AOL).
