I guess the major question for anyone who logistically wants to write a blog and have it be popular is can you write something interesting everyday for months on end? In a world where everything moves fast so the scene girl with a sidekick, a twitter, a blog, and a half naked profile picture on facebook can update every last one of those things before you can even start to hate her, its very hard to keep anyone's attention for 2 seconds.
However, for whatever fucked up reason people like to read about the mundane lives of other sad souls from every walk of life. Anyone from a washed up writer to a preteen girl can have a blog that generates reader after reader to laugh at it or sympathize with it. Anyone can have a blog that is successful but in the end who really gives a fuck. 50 years from now no one will care about what you think about Obama and no one will care about this fucking entry.
