When you look at the business relationships you already have, more often than not, having something in common with them was the conduit to the relationship in the first place.
You can learn much from people that you have something in common with - be it business or personal interests. And what's more, LinkedIn makes it easy to find people with whom you have something in common - for example your school or college.
Assuming you have entered your school or college on your profile, you can find people on LinkedIn who also went there. Try it now: http://www.linkedin.com/college/alumni
Also make sure that you have completed the Interests section under Additional Info. Don't just put in work/business interests - show your human side and include your hobbies, pastimes and passions e.g. golf, tennis, fine wine, music etc.
Then click on one of them and LinkedIn will show you everyone else who has the same interest. Then filter them by location and industry, and with just a few clicks you have a list of people that you most definitely have something in common with.
Try it now!
