I have an answer for you.
Unfortunately, I didn't get around to implementing Google Analytics until the end of December (primarily because I'm basically lazy...ask my wife), so I don't have any data for my previous podcast efforts, but here's my traffic graph from Google:
Guess...just
guess which day I put up my latest mini-podcast? (If you need a hint, how's this...I'm not here bragging about December 31.)
Now admittedly, it's not what anyone would call a standard podcast...this is the longest one I've put up so far (out of three...I just started doing this) at just over 3 minutes long. It actually has more in common with produced comedy bits that you hear on morning shows than an actual podcast. (
Here's the link if you're curious about it.)
However, I've had quite a few comments about the length...it seems that people don't have enough time in the day to listen to thirty minutes to an hour from several different sources. Just a couple of minutes, however...well, there's the graphic up there. Judge for yourself.
