The avatar versus the journalis

As Wikipedia becomes more and more like a newspaper everyday, should not the newspapers try and become more like the journalist?
Rohit Gupta's article provides some answers.

"Each person can be many avatars, depending on the diversity of his or her skill set, and can contribute a drop every now and then in the vast ocean that is human knowledge. When needed, another avatar of the same Wikipedian, or even a stray visitor, can 'clean up' some polluted part of the living document with a bit of editing. Therefore, people do not populate Wikipedia community as they do Bombay or Mexico - an online community consists of 'versions' of people, their fragmented avatars. It's more like an ant colony without ants."
