You seem to have a great deal of variety. It's also excited to see you interviewed Shona, I'm a fan. You have a quite good voice for interviewing, incidentally.
My only suggestions: You say "yeah." A lot. I'm sure you're already aware of this, so you simply need to fix it. If you can't come up with an actual response to what an interviewee says (perhaps a follow up question) even something enthusiastic like "absolutely!" would be better than yeah. it'll make your interviews my intestting and your guests comfortable.
And is there any way you could make the recordings louder? It's hard to hear what the interviewee is saying.
Overall, extremely good work and i'll be back.
PS, I can't help noticing I'm the only one to comment on here. Am I the only one who cares about Odyssian blogs anymore?
