About a month ago several news outlets reported about some lost tribe in Brazil that had not any contact with the "outside" world. I remember thinking at the time the story came out that it was bs to make that claim about any "tribe." Apparently, I was onto something, as I just saw a blurb on Yahoo! news admitting that it was a hoax.
Before I get too haughty, I should admit that I never once questioned whether the story was a hoax. I questioned only whether this tribe could actually be truly "lost" as the supposed experts claimed.
