Whether you’re out pounding the pavement, or are still gainfully employed, you need to be on LinkedIn.com!

Linkedin is one of the best resources around for tracking down former co-workers, customers, and supervisors and you’ll find it will really come in handy when you need to get an employment reference. With people moving around a lot, it’s hard to keep track of all this information on your own. LinkedIn does it for you — FREE.

With LinkedIn, you can gather testimonial quotes, join networking groups with colleagues in your field, and surreptitiously peruse job openings, just in case.

Jason Alba just updated his book “You’re on LinkedIn, Now What?” to include the latest service offerings of the site. You can purchase a copy through his website at jibberjobber.com.
