Lonelygirl15 is so awesome. I watched a few of her vlog entries when people still thought she was, you know, well, something a little more unified than she turned out to be. They were great. These guys are brilliant. They pulled a really awesome prank. Lonelygirl15 got so popular that the official websites were deemed insufficient by tens of thousands of fans, including various prominent writers and at least one Polish MP, who maintained a handful of popular fan sites, one of which, interestingly enough, was home to the investigators who cracked the whole thing wide open.

I have a friend who does similar things.
