Possibly there was, but, equally, maybe they just put the word out that they were looking for volunteers who specialised in online media and this is who replied... We don't know do we? I'm pretty certain of one thing though: no one sat down and decided that these people should all be men.
Remember, the blogger accepts that the team is not actually all men - they just chose to mention certain roles, all of whom happened to be men. I very much doubt that this is deliberate either. I posted earlier that the first few episodes have an address by Aung San Suu Kyi and contributions from Smack the Pony. I can't see anyone acknowledging this, but quite a few ready to condemn it all beyond actual reason.
