I thought it might be a good idea to create a page for the Yun on the arduino playground wiki. The Yun is just out for 2½ weeks and there are 400+ posts on the forum.
I already had to search for the Power consumption and the Build chain topics, so I thought, why not keep a permanent reference to these things on the playground?
The page is at: http://playground.arduino.cc//Hardware/Yun
If you think a specific topic is of general interest and is not covered by the official documentation, feel free to add a section to the wiki-page.
