I use it regularly. I get the following benefits from it: 1) quick way to find a supplier. 2) check out the employment history / profile / endorsements of any potential employee. 3) quick way to find a recruiter for a vacancy. 4) business networking means I can put people in touch, and they can put me in touch. 5) I'm often approached by recruitment agents regarding roles I might be interested in. Your mileage may vary though. You need contacts that have a large network and are in managerial positions to get the most out of it. No offence to anyone who isn't in a managerial position, but they don't generally have any decision making abilities so you just have to get put in touch with someone who does.
