Facebook Graph Search
Currently available to a limited number of users in the US
Pro: Powerful new tool makes it easier to get information from other Facebook users. Instantly find people with shared tastes and interests, quickly locate photographs and get feedback on products and services.
Con: Limited to searches for people, photos, places and shared interests; users can’t search general information contained in Facebook postings. Much shared information is shallow and of limited value. Could compromise the privacy of many Facebook users.
