Youtube appears to be a culture all its own.
I searched for Noho girls only because I was curious... didnt watch a single video, the channel page didnt induce any further interest (for me).
The NoHo girls are apparently some girls living in North Hollywood, that videogg? video catalog thier lives? They have thier own "channel" on youtube, probably have a following of sorts.
I visit youtube whenever someone posts a clever video, thats about it.
Actually I wasnt entirely truthful, I have no idea who that Brimely girl is, but Mary Newman is an actress and has been in several movies.
I doubt she'd waste her time on YouTube, at least in recent years.
