Everybody knows youtube. The other day I stumbled upon securitytube. A site with currently more than 165 video's about security and related items. Yes, I like video as a format. I enjoy reading but if a video is as it should you can learn a lot. I learned quite a lot from Irongeek his website too. And of course on youtube you can find some interesting stuff. If you like to watch a nice tech-show check out Hak5.
I like to listen to podcasts as well, one of my favorite security podcasts is PaulDotCom.
If you have interesting websites, podcasts, RSS feeds, ... share them with me :)
