I've listened to quite a few. He's hit and miss. Some of the material he discusses can be very interesting other times he just waffles on playing to his audience knowing well they'll lap up any old nonsense he comes out with.
His live podcasts are the same, some guests are excellent (Bernadette Devlin McAlisky) others I wouldn't even bother to click the intro (Louise O Neill).
I like him in general though, he's a smart lad who has found a niche for himself and he's milking it for all its worth. Good on him.
He also gets under the skin of cranks and tossers so that's always a plus in my book.
