Open Culture is probably the single most annoying blog railgun, popping out up to seven daily updates via Facebook or mail.
Some of the material they link to, however, is top notch.
– Like this one, for example:
A recording of an university class focusing on the big English 18th century poets.
Although this is obviously not a professional recording, but rather a nice gimmick for students that attended said course, it deals with topics on which audiobooks and in-depth speeches are notoriously difficult to find.
So, it may well be worth a look, if you’re looking for new fodder for your mp3-player.
