I have produced a number of podcasts using the Linux operating system including the Linux User Podcast. My current podcast, 5 Minute Dharma, has had over 42,000 total downloads.
They say that content is king. If you are going to do a podcast, make sure you know what you are going to do it about, that the content will be engaging, and that you will be committed to producing quality content. I will warn you, podcasting is hard work. I have burned out a number of times.
At the bottom of this post I list the basic equipment I use. I connect my Mic to my mixer, and my mixer to my computer using the Audio Interface. I record on my computer. If you are doing longer podcasts, you may want to invest in a digital recorder. My podcasts are 5 minutes long, so if I loose it, I can just record it again. You will eventually loose an episode or two.
Mic placement is actually very important. You want the Mic close to your mouth. I put mine under my mouth slightly to eliminate popping sounds. Experiment for yourself and see what works for you.
The primary Software I use to record and edit is Audacity. There are a number of YouTube videos that can help you learn how to use it. After I record an episode, I use compression and light noise reduction in post production. I then export it as an mp3 (Constant bit rate mode at 128 kbps).
I then use EastTag to edit the ID3 tags, adding further information, including 300×300 cover art. After I save the edit, I upload it to my file-server.
I use WordPress for my website, it is by far the easiest for podcasts. I use a plugin called PowerPress that makes the website podcast ready. There are a number of YouTube videos on using PowerPress.
You also want to make sure your podcast is iPhone, iPad, and Android friendly. I use the WP-Touch plugin to accomplish this.
Of course you also need to come up with cover art for your podcast. iTunes wants a 1400×1400 image, while others want 600×600, 300×300, etc. I use the 300×300 for the mp3 file.
Finally you have you get the word out. Besides you RSS Feed, I recommend getting into iTunes, Stitcher, TuneIn, Blubrry, Miro, and many others. The majority of my listeners are from iTunes.
And don’t forget social media. The big two are Facebook and Twitter. But you might want to consider others such as Google+, LinkedIn, and Pinterest.
