I am not one to look at my link counts at any of the search engines these days. But I always recommended Yahoo!'s linkdomain command if people did want to check backlinks in a search engine. The syntax is simple, you type into the Yahoo! search box, linkdomain:www.domain.com and press go.
It looks, like perhaps, Yahoo! is taking Google's approach by only now showing a sampling of all your backlinks with that command. Google went through a ton of negative PR (no pun intended) when they started doing this. Yahoo! was then praised when they announced the prerelease of Yahoo! Site Explorer which is suppose to tell us information about a sites backlinks and so on. But if this linkdomain command, in fact, has been reduced to a sampling of your backlinks, it will become as useless as Google's link command.
