|There's always been "Flavour-of-the-month" no-talent celebs even before the Internet. Tila Tequila is an example of Post, Jo Guest is an example of Pre. They were famous for getting naked, not because of the medium which carried them (Internet and Print, respectively)|
Some people get famous for being famous or for capturing the essence of a fleeting meme. Whether it's the internet(TT), "news"(Joe the Plumber), commercials(Where's the beef?), radio(Crazy Frog) print(Jo Guest) or some hybrid of the previous examples(Samantha Fox), the result's the same. The internet argueably makes it easier to become "famous" but look at the numbers: There are Millions of mySpace and Facebook posters, only a handful T. Tequila's. Millions of youtube posts, only a handful of "virals"...
The no-talent will rise sometimes regardless. Let's not forget: the definitions of "talented" or "famous" are subjective...
