Welcome to the NephMadness PodCrawl
The idea behind a podcrawl is for a variety of podcasts to coordinate on timing and topic to push a theme and get each other’s listeners to explore all of the podcasts. One of the first goals behind NephMadness was to build a community and in the early years of Twitter, NephMadness was central to the formation of #NephTwitter and defining the ethos that makes our online community kind, intelligent, vibrant, and interesting. The NephMadness Podcrawl hopes to inspire and grow the nephrology podcast community in the same way. For 2023, our second year, the PodCrawl has assembled the Avengers of Medical Pods!
