Internet Fame and its relation to the public world

As Patricia Lange discusses throughly, the use of the internet has and continues to redefine the meaning public and private space. She says that, " public and private are relative terms and shift according to individual perspectives." Be that as it may I assume that most people would describe their homes as more private than say the grocery store or movie theater. Still through videos and social networking sites we invite people into an identifiable personal part of our lives. As witnessed in the case of Tila Tequila, those willing to to advertise themselves more openly can in strange ways reap the benefits of their vulnerability.
Tila Tequila's half-naked photos on myspace are arguably part of her professional life, but the fact that she has a profile and many many friends adds the personal facade that I think myspace thrives on. Men and women, young, old, gay, bi, straight all friend her, maybe because some of their friends have, or perhaps just because she's a hot item. Her popularity has no doubt soared, largely due to her internet personality, demonstrated most clearly by the trashy reality dating show she starred in on MTV (where's the music?). The internet has provided this incredible space to be your own publicists because, as Lange also talks about, public is no longer bound by geographical space. Information can be exchanged between people most everywhere.
I haven't decided yet how I feel about this outlet. It is sort of an extension of the disgustingly fame fixated world that already exists but does it even the playing field? Has the internet made it more possible for the average Joe or Jane to become the next big thing? Is that a good thing or does it simply lead young women to take their clothes off for myspace because they see that this gets results? It seems to me that while the internet does change what public means the same social issues of exploitation exist on the level that everyone can access as do the ones that exist on a smaller scale. There is the same 'get ahead at any cost' dynamic. I'm not implying that Tila doesn't have the right to pose scantily clad in front of endless viewers or star in a show about being horny bisexual and looking for love. I'm just curious as to why people are so drawn to this behavior that they want to be her friend, even if that is a loose association.
One interesting possibility that arises from internet celebrity is the potential for viewers or consumers to decide what they enjoy instead of a company packaging a celebrity to be popular. Think of how Andy Samberg's part in the O.C. parody led him to SNL and eventually movies. I think the fact that public isn't confined to one place and their is this great information sharing allows for a legitimate qualification of what is popular across ethnogeographic boundaries.
