Well an easy way that I have found to find good podcast is using a tool called Rhythmbox, its an audio player for linux which you can use to find podcast. I have found a lot of podcast using this tool, such as BBC News. Its a great tool I think!

Hi, I recommend you to try "Effortless English" system which helps you improve not only your listening skills, but also your speaking. I think it is amazing method, at least, it helped me.
