I spent a lot of time watching it last night and a bit today too ... truly awful occurrence.
While far from pleasant viewing, the Internet has played its part big time here. While standard communications seemed to be badly affected amazingly some people in Haiti had internet connections and were able to use social media such as Twitter and Skype to contact the outside world.
These links I found very useful, if sober, viewing.
CNN Live - gives a good general overview. Had a lot of coverage up to this afternoon, they'll prob have more later
Facebook Site with 38000+ signups. Heartrending stuff seeing so many enquiring as to loved ones here. Came across one today where a woman was looking for rescue assistance to search hotel rubble for her husband and 3 kids and she was able to hear her daughter crying. I emailed the US Embassy in Haiti with her message on Facebook in the faint hope it might get picked up or acted upon
This made for riveting viewing last night & today. This guy Pierrecote is in Montreal and spent 14 hours online chatting on occasions to people in Haiti by using Skype enquiring about missing persons for people and getting info re general damage. Major Broadcasters such as CNN were onto him. People also acted as translators for him into English, French and Creole in the Chatroom. He might be online later tonight.
