Some quick pointers on how to sound better in a podcast format:
1) Short podcasts do not need an intro/outro, but longer ones should
2) Throw a blanket over your head if you cannot record in a sound booth
3) If you need a mic, Blue Yeti's are "plug and play", easy to use and have a TON of YouTube videos that will show you how to use them
4) Use a pop-guard and/or turn the mic sideways to avoid harsh "p" sounds
