Purpose (or What's the point of social media these days?): in the 31st episode we get in-depth about social media and discuss whether we're in the (as yet) undefined third age of the tool and what that means for our businesses; but it's not all deep and meaningful (phew!) as we also talk about shilly-shallying, how many eureka moments have been lost to impatient dogs, whether it always rains in Wales, the trouble with (some) vegans and the Marvel infinity stones. And llama videos. Obviously.
