Some may know about the Geeko’s Tube, I’m not so sure that many do though. There has been for a while now tube.opensuse.org, this is the official repository of videos by openSUSE people. All the video is in .ogg format, and as such will play straight out of the box regardless of whether users are purists/pragmatists/whatever.
There are several services out on the web that offer video streaming in flash, one that caught my attention is blip.tv. So why is blip different to YouTube et al? Well for starters they openly use Open Source (they’re not ashamed of it), they support multiple formats for uploading and playback, and they provide multiple mechanisms to get your shows out there.
After some consultation on the mailing lists and IRC, I have created an openSUSE channel on blip.tv - http://opensuse.blip.tv The aim is for videos by the openSUSE Community for the openSUSE Community.
