There is substance in the humour of Gervais, however, you obviously do not get it. If you can't appreciate 'The Office' it might be time to stay away from all things comedic. Hey, humour is subjective and there's no accounting for taste.
You would seem to be in the minority as far as Podcast downloaders are concerned; 'The Ricky Gervais Show' is considered to be the world's most downloaded Podcast.
Also, I do have some news on future episodes. It seems you'll have to pay for them this time (if obtained by "legal" methods). According to
this article from TechDigest:
No longer available via The Guardian, The Ricky Gervais Show will be available only from Audible.co.uk and the iTunes music store, with the first episode online from February 28th.
