The new Microsoft search platform lets you see who's linking to a site via the "LinkDomain:" operator. For example, "LinkDomain:rimmkaufman.com" shows all inbound links to rimmkaufman.com.
Now Microsoft also offers the "LinkFromDomain:" operator, showing you all the outbound links from a domain. For example, "LinkFromDomain:rimmkaufman.com" shows all outbound links from rimmkaufman.com.
Neat stuff, and a good way to keep an eye on your competitors' inbound and outbound linking.
