As per the post of Yahoo! Search blog on Aug 1st, 2008, Yahoo! announced that useful SearchMonkey application including Yelp, Yahoo! Local, and LinkedIn are turned on for all search engine users. Now, the Yelp, Yahoo! Local and LinkedIn Enhanced Results will automatically appear in the search results, eliminating the need for users to go into the Search gallery to add them. You can add or remove these enhancements from the Yahoo! search preferences link.
In addition to this test from Yahoo!, users can see the option to add the LinkedIn Enhanced Result directly from the search results page with the option to share the link with other friends too. Nice one! I say.
