Open Culture has a sort of blog format on its website. It claims to be the "best free cultural & educational media on the web." As far as that goes, I can't say. I can say they have some nice educational tools highlighted. Much of their content may just be organizing and pointing out resources on other sites such as iTunes but it is helpful information.
Perhaps one of the attractive free resources that they highlight is free audio books. This is a great boon to ESL students or 1:1 laptops schools. Students can access a number of books via their iPod or computer. They also have some free digital books on their site which are available via creative commons (which I discussed in the previous post).
