In the past, creating a Podcast has been several involving processes. I just leaned about Cinch, which offers a super easy way blogger to create interesting Podcasts just with a phone, and very few easy steps 

• Call (646) 200-0000 from any phone that has user-ID enable (the service requires your phone number to identify you). Using Skype would probably not work.
• Thats it! BlogTalkRadio puts out a podcast feed with an MP3 at a pre-defined URI. Just visit http://cinch.blogtalkradio.com/number_you_called_from   (replace number_you_called_from with your phone number)
• Use some sort of a plugin for WordPress to import the said feed into your blog and you be podcastin’! at no time.
