Two of the attribution requirements in the data dumps are:
2. Hyperlink directly to the original question on the source site (e.g., http://stackoverflow.com/questions/12345)
4. Hyperlink each author name directly back to their user profile page on the source site (e.g., http://stackoverflow.com/users/12345/username)
This is impossible (without violating the spirit of the requirements) for failed sites like Gadgets, as there's nowhere to link.
