Often times on Facebook I see my network asking their network if they know anyone at so and so company.
But there is an easy way to check that premise with a ‘friends of search’. Let’s say I wanted to see which of MY friends are friends with anyone at IBM for example.
From the search box I just typed in the following query: friends of friends who work at IBM
Voila! Instant results. With all the attention of using third party tools to search Fb sometimes we forget the site itself.
