[...] when there's something big on the horizon like E3 it makes sense to beef it up, and when there's nothing interesting to talk about it's fine if the podcast is just an hour long.
What I meant to say is that don't stop it at 1:15 if the discussion flow is going great. If nothing is going on, then 45 min is great
Podcast length is something that was important when there was the possibility that some of the shows where going to be shown on SPIKE TV. With today's way of watching shows on demand the length of a show is less a factor; And honestly I don't know why you would limit yourself to a running-time. Like many here already said it makes more sense to have a longer podcast for when you have something to talk about (during E3 & Christmas) and a short one when there is nothing happening. Like I always want to hear more Love&Respect, but because that is the last segment it always feels rushed. Kyle often skips questions and I myself have to wonder what patrons wanted to know. Use your best judgment which questions you ask. I generally wouldn't cut of a discussion even if you talked about that topic for 20min already.
TL;DR: If there's nothing new make the show 30min. If the Gaming-World is on fire make the podcast 5hours long. Same goes for FrameTrap BTW.
