The Power of a Word: Trigonometry

I've taught math for years and I do not know the number of times that the mere mention of the word Trigonometry would stop  math students in their tracks.  For me, the phrase podcast stopped me in my tracks.  I've put it on a pedestal, made it the keystone, and freeze every time I approach the topic.
When we started exploring podcasts, I found NPR audio tapes with written transcripts and videos from Morning Joe as podcasts with RSS feeds.  I was still baffled:  could a podcast simply be an audio or video embedded in a website?
I started by finding a basic definition of podcast using Wikipedia as a basis.  Wikipedia called a podcast "a type of digital media consisting of an episodic series of audio radio, video, PDF, or ePub files subscribed to and downloaded through web syndication or streamed online to a computer or mobile device."  Was I really that math student intimidated by the word Trigonometry? Did I allow my ignorance hinder my progress?  Was I already creating screencasts and videos and the only thing keeping me from the podcast was the creation of a serial, syndication and an audience?  
Honestly, this annoyed me.  I visited PodOmatic and created a free account and in less than four minutes I created a small podcast; rather, one 26 second episode.  That was it.  This user friendly site allowed me to record audio, pair it with a graphic and in 26 seconds.  My ignorance paralyzed me, and I allowed that happen.   Not knowing something is normal; not taking the initiative to educate yourself is the problem.  In the Wizard of Oz, Dorothy, the Tin Man, the Scarecrow and the Lion went to the Wizard for help.  Based on the knowledge they were provided, they believed he was the 'Great and Powerful Oz'.  Did that make them stupid; no, rather they were misinformed.  Once Toto removed the curtain, their ignorance was changed to knowledge:  the Wizard was just a man behind a curtain.  PodOmatic was my Toto and my first episode can be heard here.  It is a very plain audio file, but it is my first step.  The success is in the fact that I took the step.  Tomorrow is another day, and an opportunity for another step.  There is still fear involved, but curiosity is creeping into the picture.  What could happen if I used Snagit to create screencast videos and translated those into a PodOmatic episode?  My 'what ifs' will soon out weigh my doubts and I will be able to fully experiment with this new technology.  I am so thankful that I tried.
