Joomla offers flexibility regarding the type of contents and podcasts are handled by Podcast Manager, a great extension. It also features EasyBlog 5 to allow the podcast journalists to post more personal articles (such as Japanese recipes…).
The use of J3, PM and EB5 allow the journalists not familiar with IT to easily publish rich content.
I also wanted something responsive and with good look, and I'm no designer. The Joomla environment features lots of great template designers and I chose to use one from JoomlArt. The features of the template, its ease to use and weight were important into the decision making too.
