Whoever catches with the technology first is the one,who earns more.
There are so many ipod, iphone viewers on digit and the word of mouth will def make sure that digit will atleast get more than thousand podcast listeners.
Its high time Digit jumps the bandwagon before anyone else does.
Podcast will add more subscribers to Digit.It will be accessible to the entirely new medium.
All my vote and reasoning for Podcast on Digit.
