If the podcast was 2 hours long, then perhaps a introduction could serve a point. But since they are doing a short version, it should really just be sweet and intense since they will have no problem keeping peoples attention for that short period of time.
For me, it's the guys behind the podcast that maters and not so much the topic at hand. When listening to a podcast you want to be invited to their world and you trust the producers that the whole show will be interesting in terms of opinion and content. The same principle applies if you go to the movies or theatre.
If they have to present every subject at the start to keep listeners hooked, then they are doing something wrong. The intro works the other way around for me. If I know that a topic that don't interest me will come up last, I will never finish the podcast.
Better to keep the suspense and option for surprise throughout the whole episode. Then again, it's ECL-talk so everything should be pretty, pretty interesting to begin with.
No need for the boring introduction. Just my opinion.
