Clever, Quick, Informative

Very useful information! Great stuff to understand and start conversations with. The speed of these topic run-throughs are timed quite well and it is easy to comprehend. The scripting is very clever, with good jokes and an engaging format. Also, that Gooey Decimal System joke? Just… perfect. The amount of ads aren’t too bad either. Thanks Ashley and Cody!

Greeking out lover ,

I love this podcast

Thank you for putting so much work into these episodes I have learned so much from this podcast. I hope you continue to make more and more

Bye

Who needs a nickname??? ,

Maybe good for children...

I love science podcasts, but this one seems to be geared more toward children rather than adults. I just cannot endure the exaggerated, sensationalistic presentations (and don’t think that is good for kids either).
