I would say yes, though I have listened to this year in full and only cherry-picked pre-2006. I can't pinpoint it, either. For me, it's always been very consistent, and arguably this year is not as 'innovative', with (seemingly) more guests and less 'crazy' or 'character' shows. There are more genuinely laugh-out-loud moments per show. It also seems a lot friendlier and accessible too.
