Tried to do commentary on the very first broadcast but it was hard to hear the audio coming from the game. I could go back and try and improve that setup so the game audio is more clear/less white noise, but that's something I'd have to work on. Right now it's just me and H4 working on the channel and we're barely broadcasting as is. If we had like say 5 people broadcasting then surely we could get one broadcaster to setup commentary. Another thought I had was to buy an audio mixer/soundboard or get a microphone with L/R audio output. Although that might not go smoothly since it would probably end up being two different audio sources with the mic, one in each ear if you're wearing headphones. The other option would be to record audio commentary and layer it on top of recorded video but if I went that route I'd make it more purposeful like teaching/explaining etc.
Skype poses problems as well. If you're watching and doing commentary, it's going to be delayed commentary if I opened up skype on my end and fed it into a mic. Broadcast has a several second delay, so if you make commentary on what you see on the channel, you're watching something that happened a moment ago live for me. For instance, whenever I check the channel after finishing an audition, usually it's displaying the middle segment of the last appeal round. So if you were to say "yay Yukiho won the audition," your audio would probably show up delayed during the TV appearance.
I would show some DS stuff but I'm not a big fan of the system nor the DS version of im@s

Sure it could get mentioned or do a short thing on it before it comes out, but I don't want to generate a hype wagon for something I'm not personally interested in. Hence why I'd be cool to have more people participate, so those who do get that version could show it off or those interested in it could talk about it.
