But i have to admit that you actually have a very nice tone in your voice that suits a more professional broadcast or voice over.You would nail it with such an ease I'm not kidding here. Also you have a nice personality for radio or podcast types..
But, if you want to get serious about this, and i hope you do and you will, you have to consider limiting the use of "so" and the "like" ..in addition to that write down the main points you want to discuss so you won't get lost in your podcast. So for this as
a trial I think your tone of voice and character is very suitable for radio/podcast.
Why not start a duet pod with your crazy friend ? you guys get along quite well :D
