LinkedIn

I constantly recommend LinkedIn to people as a way to connect with people around work-related issues. I have a profile that makes it easy for people to see what I'm doing and what I've done in the past. I have a network of people to whom my contacts can connect, for information, interviews, references, services - you name it. I know people who've gotten jobs through reconnecting with former employers or colleagues. It's simply the most relevant networking site out there for professionals in any field.
