"Are you asking what is the connection between icebergs and podcasts? Well, everyone knows that we only see the top of an iceberg floating on the sea, the vast proportion remains hidden out of sight. Podcasts listed in podcast channels are sometimes like icebergs too, especially when RSS feeds are listed in podcast directories.
As podcasting becomes more popular and used to retrieve information (albeit in an audio or video format), the number of podcasts can become large and unmanageable. Some podcasts feeds are now starting to contain more than
300 episodes. So using techniques to search and locate podcasts also becomes an important skill for children and young people to use."mehr
