Two videos I highly recommend watching, if you have the time…
Also check out this lecture debunking myths about statistics in developing countries, its long but brilliant. You’ll need FLV Player to watch it on your computer – which is available for free here. Or just watch it online.
Incidentally I found this video on the YokWay social network, which is one of the better content geared social networks I’ve seen lately. Its in Beta currently, I have 10 invites to give out though, so comment and let me know if you want one.
Update : Part two of the Aurora video is online now here.
Another Update: All four parts of the Aurora Series are online here, courtesy Lifehacker.
