What is a Blog?
A blog (or weblog) is a website in which messages are posted and displayed with the newest at the top. Like other media, blogs often focus on a particular subject, such as food, politics, or local news. Some blogs function as online diaries. A typical blog combines text, images, and links to other blogs, web pages, and other media related to its topic. Since its appearance in 1995, blogging has emerged as a popular means of communication, affecting public opinion and mass media around the world. Blogs can be hosted by dedicated blog hosting services, or they can be run using blog software on regular web hosting services. For more on this click HERE.
What is a Podcast?
Podcasting is the distribution of audio or video files, such as radio programs or music videos, over the Internet using either RSS or Atom syndication for listening on mobile devices and personal computers. The term podcast, like "radio", can mean both the content and the method of delivery. Podcasters' websites also may offer direct download of their files, but the subscription feed of automatically delivered new content is what distinguishes a podcast from a simple download or real-time streaming (see below). Usually, the podcast features one type of "show" with new episodes either sporadically or at planned intervals such as daily, weekly, etc. In addition to this, there are podcast networks that feature multiple shows on the same feed.
Podcasting's essence is about creating content (audio or video) for an audience that wants to listen when they want, where they want, and how they want.

I find that the best way to subscribe to a podcast is by using iTunes. Download it for free HERE.
