Today, while i was at work looking for help implementing certificate services on a windows server 2008 box, i came across Microsoft's newest technet site. technet edge is a place where IT professionals go to get the inside scoop on the latest and greatest technologies. You can do stuff like watch screen casts, check out interviews with people who develop the products, connect with your peers and speak what’s on your mind.
The video content certainly isn’t enough to get you through a certification exam, but i found most of them full of very useful tid-bits about new technology. What more could you ask for for free!
