Some of you have been asking what has happened to the backlinks.
Here's a message from the Site Explorer Product Manager:
"We are working with the Microsoft team to ensure that webmasters can continue to use Yahoo! Site Explorer to view inlinks (a.k.a backlinks) to a given webpage or a website and to further be able to export them as CSV if desired.
Please note that this functionality will be available only through the Site Explorer UI and not through the Webservices API.
