Actually I don't fully understand why would you search for the term "Linkedin" alone... I mean if you want to learn about Linkedin, you could go straight to Wikipedia..
Anyway this is what I have found.
Users searching for your term also searched for these queries. You can sort by the following metrics:
* Top - The most popular search queries. Scoring is on a relative scale where a value of 100 is the most commonly searched query, 50 is a query searched half as often, and a value of 0 is a query searched for less than 1% as often as the most popular query.
* Rising - Queries with the biggest increase in search frequency since the last time period. Results marked "Breakout" had a tremendous increase, probably because these queries are new and had few (if any) prior searches.
