Today I found out about LinkedIn. This will be about the third one of these user address/friend-of-a-friend things that I’ve signed up for, and this one actually seems to be the best. With three contacts, I’ve got 21k+ networked users that I can search by company, name, skill, profession, etc. You can also endorse people. Funny thing is how many of my contact are already in here.

LinkedIn is a networking tool that helps you discover inside connections to recommended job candidates, industry experts and business partners. Through LinkedIn, you can accelerate your business effectiveness and career success by leveraging the network you already have. LinkedIn makes it easy to receive and seek out opportunities through your extended network while protecting your privacy, your inbox and your existing professional relationships.
