Was the data included in the purchase of the sale?
I am looking at the login page and it seems to require Facebook authentication, and not even an option to use my old Digg.com account. In the FAQ it implies that eventually the old data will return.
I'm starting to feel like they decided to release a work-in-progress to capitalize on the wave of press they've received due to the sale. Most people had high hopes for the new management, and releasing early with a product that is less than half finished really causes a smell.
