To me it looks like viral marketing since the vids are too professionally edited and there is lighting in the videos. As Well as the videos follow some story which seems scripted.
If you dont know what im talking about.. Go on youtube.com and search for lonelygirl15. lonelygirl15 are the most viewed videos on youtube.

There is also a website for this chick (marketing thingy) registered by a proxy to hide real owner as well as it was registered bewfore her 1st video was posted youtube:

Watch some of the videos and you can tell its scripted and fake, but not sure what the point is.
