<<Orkut continues to undermine Google’s Data Liberation Front, whose singular goal is to “make it easier for users to move their data in and out of Google products”. Earlier this month the Orkut friend exporter, which makes it easy to export your friends’ contact information to a standard CSV file, was mysteriously broken due to a bug. The timing of the bug was more than a little suspect — Orkut has been hemorrhaging users lately in India and Brazil as people flock to Facebook, which takes advantage of Orkut’s friend export tool to help users make the switch. Now Julio Vasconcellos over at Armchairfounder has noticed how Orkut managed to fix their bug while still making it harder for members to switch to Facebook: the tool works, but it no longer includes your friends’ Email addresses.>>
