I do not know what program Nikonians is using to produce Podcasts. I will send a question as a Nikonian Member in the Morning. It is a standard Mp3 format when I download the programs for listening. If you decide to podcast make sure you get a good microphone for good sound quality.
Just making the suggestion has gotten my wheels rolling. I will be High Country scouting this year in the Ruby mountains of Nevada. I have a 5 man team - group hunting for Nevada Mule Deer this year. I will also be photographing during scouting and hunting. I hope to compile some good presentations, perhaps including a podcast also.
There is another site called PodcastAlley.com -- The place to find Podcasts
Those guys have an entire section dedicated to podcasting at the top of the home page.
You can send a question to Nikonians at the Nikonians Contact page. Visit: Get in touch with Nikonians
Let me know if you get good info and I will do the same for you.
