I want to do this too, but I am really shy and have a hard enough time talking to people in everyday life, I can't imagine having a camera pointed at me where all I do is talk....but I wish I had the nerve to do it.
You should do it! I'm in the process of creating videos for a channel more music based, but I plan on doing vlogs and stuff too. Then we could be two witty girls who took it to youtube and do collabs and stuff
