I have always been in favour of brevity. I guess it is due in part to my training as a journalist to report news in as few words as possible.
It was a hard lesson when I first started out as my editor would tell me to cut my 1500 masterpeice to 450 words. Cut, cut, cut, cut!
There is no such demand from anyone when it comes to podcasting; people do ramble on and on for hours at a time in some cases. But frankly, I don’t have the time to listen to them all the way through and I wonder if you do too!
So when I am asked “how long should my podcast be?” my answer is that there is no rule, how long is a piece of string? But ultimately; make it as short as possible.
