A podcast would be great! What were you thinking of doing, just the same as the blog, or making it more medically oriented or more personal? I listen to the Pre-Hospital Trauma Life Support (shortened to PHTLS, thank god), don't know if you've heard of it, it's basically an american paramedic talking about the different treatments and injuries encountered in pre-hospital medicine. Something like that from you might be good, but equally the less clincal nature of your blog would be ace as a podcast as well. So basically I'm saying i'd love to hear it, whatever you did!
