Ask YouTube for Ogg support!
This piece of Ogg activism is getting some traffic on identi.ca and Twitter right now. If you haven't already, you should jump in.
YouTube is, obviously, the largest source of videos in the world by far, so keeping pressure on Google to support web standards and free formats (over proprietary formats like Flash) is really important.
Google has closed the window on HTML5 feedback, saying that peoples' voices have been heard. However, notably absent is any mention of Ogg. Google leaving Ogg out of the picture here makes sense, because it would be very easy for them to offer HTML5/h264 videos that play in Chrome and Safari, while still excluding free formats and users of free browsers like Firefox and Icecat.
It also means that, from our point of view anyway, votes for Ogg Theora support are still welcome. PlayOgg can play an important role here by stressing free formats.
If you don't already have a Google account, please don't let this encourage you to make one. You can call YouTube at 650-253-0000 and make the same request there.
Make your voice heard! And tell a friend.
