Human beings generally have ten fingers. In what is probably not a coincidence, the world’s most popular number system counts in base 10.
And so, due to what was essentially a series of evolutionary accidents, the largely meaningless fact this is our 100th episode feels like A Big Deal.
But I’m a huge fan of meaningless celebrations, especially when they’re about myself. So this episode is by way of a sort of party. Former co-host Stephanie Boland is back, with one of those city quizzes she sometimes makes me for podcasting purposes.
We also have brief guest appearances from four friends of the show – my other former co-host, Barbara Speed; Centre for Cities economist and mackem Paul Swinney; Guardian journalist and noted train nerd Jim Waterson; and Skylines’ biggest fan, in Brazil or anywhere else, @AngrySigh Julia – each with a question for the two of us.
