The Olympics have a good presence on Google+, if that is your preferred social network. Be sure to follow the official London 2012 Google+ page, the Olympic Games page and the NBC Olympics page. While each of these has a presence on Google+, the coverage appears much more robust on Facebook.
For video coverage of everything you might miss during the work week, check out the official channel of the U.S. Olympic Team on YouTube. You can browse videos of "gold medal moments," Olympic coaching tips, clips of returning veterans and more.
There's also the official Olympic Channel by the IOC, where you can sort videos by sport and country, and view the events on tap for the day. You'll also notice a link on the top of this YouTube page where you can watch the Olympics live in the U.S. on NBCOlympics.com.
