I've discovered the YouTube leanback function - Sweet!

The system is great for reviewing YouTube subscriptions quickly - to be honest I couldn't be bothered with looking through the subscriptions at all before (a bit like Twitter in fact). I've used the free Android YouTube Remote app - which is very intuitive to use.

Subscriptions
The German subscription channel Deutsche Welle is particularly good and there is always something well produced and interesting (http://www.youtube.com/user/deutschewelleenglish).
The main Deutsche Welle website is also great and has free online language courses. I suppose the British Council does something similar but somehow it didn't seem as industrious as D-W!? The British Council's presence on YouTube seems to have more of a country focus for example http://www.youtube.com/user/britishcouncilhk and http://www.youtube.com/user/BritishCouncilUK
