I have recently started my own Podcast. The name of the show is: TREKS in SCI-FI. The focus of the show is Science Fiction entertainment, Star Trek, and collectible reviews. It is now listed under iTunes Podcast section. The main website is here: TREKS in SCI-FI (http://www.treksf.com)
I have three shows up so far. Take a listen sometime if these subjects interest you. :)
