A friend who fled New Orleans and Luling, Louisiana showed me his webcast on Ustream. Ustream allows Mac and Windows users to share their video on a Ustream page. Unlike broadcasting a live feed straight from your computer, Ustream can handle thousands of visits, as my friend’s page had before his house lost power when hurricane Gustav hit Louisiana this morning.
Another service like Ustream is Stickam. Both are free so I suppose their business model is to just be purchased by Google.
If you have a webcam and a nice view from your window, give Ustream a try. Or you can just use it to watch emergencies like this.
Best of luck to everyone in the storm.
