@PauperPeter Ah, but it's not a matter of hierarchy. It's simply that some people only "need" 30-45 mins, while some others "need" 3 hours due to what needs to be discussed.
Millenniyule interviews have a 120-minute slot, so most end up lasting about 100 mins. Sometimes I think an interview should have been much longer. In future, some nights could have a new format: some short interviews (30 mins) and a long one (2-4 hours).
Unfortunately, Chris Brunet has had to cancel his appearance tonight. His slot has been taken by the Delphica Society.
@MartinLichtmesz, on the 26th, has been moved two hours earlier.
