Bit of a delayed response to all this; Had to reformat my laptop over easter, as it wasn't working well before the start of newsjack and by the end I had a good 60% chance of it blue-screening on boot...
Still, belated congrats to everyone who got on, even more congrats to those who kept submitting despite not making it; at least we all seem to have fun writing for it (mostly).
An as a final point - Dave Cohen's doing a 'Writing comedy for Radio' course in a couple of weeks which apparently still has a few places left. Seems like it should be pretty useful if you're trying to write for Newsjack - more here.
