This is great, and keeps progress alive. However, keep chuggin with what you have. Let is simmer a little bit longer. The interviews are getting better (vid quality and content). Certainly you guys need your internal processes, but what I see I like.
For Lenn not being on IM. I wouldn't know how you do it. I have very few "friends" and even fewer contacts and still I get at least 10 IM's by 9:30am. Keep it up brother.
