It's a nice tradition because you get to break the rules of grammar. Also you make less keystrokes. The attitude of the oral tradition is that writing is a medium of communication, and if your message is clear then nothing much else matters. The reason why it's good for the Web is that it's informal and often quite personal. This compensates for the fact that computers are highly technical and impersonal.
TV has a similar problem but overcomes it through the personality of human voices.
On the Web the only way to compensate is through the personality of writing. Whether it's easier to write in the oral tradition than formally is a moot point. Skill still matters. A good piece of journalism online will still grab you whether it's oral or formal or broken up or in one big chunk. It just picks you up and carries you through to the end without you even noticing.
