Reading these blogs is like looking in a window onto another's life. You could call it the reality show of the internet. And why are reality programs so hot on television? It's because they're not about overpaid stars who get too much attention, they're about your average person. Sometimes it's a young British man studying to be a barrister, sometimes it's an Indian student and his initial experience of American culture, sometimes it's a housewife regaining her sanity during a break from her children. Many times the blogs are in another language, as people blog worldwide.
