Yeah if you look on twitter, both are in 'tweets and replies' just not 'tweets'. Same with the two gotham by gaslight tweets.OK, that makes sense - the second time I tried didn't catch up earlier.
I stumbled across this video from the Doctor Who @ 40 weekend that was recorded to promote Exile and it seems pretty clear from it why Nicholas Briggs, as the writer/director/"Previous Doctor," might have gone down the comedy route that he did at the time. I'd be willing to wager his opinion on a particular hot topic would be quite different today, based on the comments I found in print when I wrote the review. As you said, "Past is Another Country.""What if Doctor Who ended up doing a contemporary sitcom" and "what if the Doctor was a woman" don't really make sense mashed together and it's a Past Is Another Country thing that merging them made perfect sense in 2003 & people didn't have a problem.
