I tested the “openness” of the new FB architecture by searching my name together with “facebook” on Google. It turns out that every post made on a group’s Wall by a FB user is now public and searchable. Granted, these were “public” before on FB — if you went to the group’s page, the Wall posts were viewable. But only via FB, by going to the group’s page. The content was not searchable ON FB by inputting the user’s name. Now the content is in public search records. So, if a user belongs to, say, a hiking group which organizes its activities on FB, and the user makes posts to arrange carpooling for X weekend to Y event on the group’s Wall, Google will show the content in a search result if you search the user’s name and “facebook”. When I did my test run I came up with one of the many small groups I belong to. There’s my information about arranging a carpool for three weekends I will be gone over the summer, now searchable via Google. What’s upsetting is that this applies retroactively to content already created, with no warning. This will be scrapeable via search robots. A user might as well post his or her travel plans and personal information on PleaseRobMe.com.
