I'm not American either and found interesting content.
There might not be a lot of British content up there right now but give it time - I'm sure there will be. In exactly the same way as widgets were all US-centric to begin with but now you can get localised ones...
Just because theres no British content doesn't make it uninteresting in itself - thats a bit short sighted - the fact that theres no content AT ALL that YOU find interesting makes it less appealing to YOU.
it's a bit like saying - 'I love movies, but they are all pretty much american so i dont like them and they are a waste of time for me - therefore i dont go to the cinema...'
if you truly want more british content, help yourself and try google! i just did a search for 'british podcasts' - and the first hit?
