Are there any specific "Business Studies" blogs, forums, networks around?

I recently set up a blog for my senior students scholsbiz.edublogs.org to encourage them to interact with the subject outside of the classroom. The site posts assignments, sample exam questions and general feedback/advice.

Does anyone know of other such blogs that I can have a look at for ideas and to create links to. I feel like I'm reinventing the wheel or else am just very poor at googling. I've seen various sites with resources but none that have continuous blog like updates.
