That is why the typed interview is a better idea since more people would be able to participate and keep their cover I too gave it a second to think about how I sound in a potential interview. 

Anyway's you can act out your voice for the interview if it's short at least. 

Maybe a different approach where the main questions are answered in voice or the last one or the improv ones. Who knows, still not everyone has mics and most are shit quality so typing would be good. Still, voice is a good idea since it brings in another layer and I'm sure many funny moments can arise, plus it's an active form of communication and engagement.

I'm thinking both methods should be employed, the important thing is the format and the recognition. Also, it would be good to have a nice theme that doesn't repeat. Maybe get the new users to participate, help with the introduction post, something like that, maybe picture walks or something that shows the colors and the different worlds we live in. 

Basically a pumped up introduction post :D with some recurring questions:

Why are you here? How did you get here? What do you like? Where do you go? Who are you?

Having that in typed version will save you the editing. 

Now that I gave it some thought it would be better as a community venture. 

More interviewers and more interviees we really should talk about that "guild" busniess. 

I'm just musing around.
