[PodcastMN] ideal podcast length

[Martin Grider]

Hello,

Long time lurker here... my friends and I are finally starting to get
our podcasts posted (we did our second one last night). Our first
podcast came in around 55 min, and the second was 1:08. My wife thinks
this is too long.

We are definitely quite "newbie", and so far have done little to no
editing. (This is a very conversational toned podcast.)

Anyone have any pointers to data about ideal podcast length? I'm
interested in everyone's opinions also, but some kind of "resource"
link would be ideal.

Thanks in advance for sharing any collective wisdom!
