Ooh! Ooh! Ooh! Good idea and look what I found!:
AvPNews Interviews Searched late 2003
PlanetAvP Interviews Searched late 2007
I'm currently searching at work and don't have a ton of time to read right now but I'm hoping these have the kinds of stuff I'm looking for. If nothing else, having the names of some of these developers is really helpful and maybe some of these people are accessible via social media. It's crazy how much the internet has changed since that game came out.
EDIT: So far disappointed by the AvPNews ones. The Dave Stalker transcription from what appears to be a multiplayer lobby chatroom is amusing at best, but there's not a whole lot of info. His sarcasm is coming through in some of his responses and it's pretty entertaining. I can totally see myself as one of the people asking him these annoying questions like "When are we getting more guns!?"
