Have you listened to the 'We Have Ways of Making You Talk' podcasts, mainly on World War 2 history that James Holland does with Al Murray? They have over 500 episodes now, including several on tanks and small arms.

No, podcasts are in the same category as social media as far as I'm concerned - life's too short!

Some podcasts are definitely worth the time.

I know exactly what you mean about social media, however I quite like to listen to podcasts whilst having my daily stroll to get a bit of exercise. The 'We have ways' podcast does seem to have more adverts at the moment, however I am prepared to tolerate this as it is free.
