Blogging: Quality Not Quantity?

There was a recent piece in the NY Times which piqued my interest about blogging called "Blogging at a Snail's Pace." The piece opens with some anecdotes about "slow bloggers," people who employ the tenets of the slow food movement (which is built around the notion that fast food is killing us in more ways than one), in their Web presence.

Author Sharon Otterman writes: "Slow food advocates, like the chef Alice Waters of Chez Panisse in Berkeley, Calif., believe that food should be local, organic and seasonal; slow bloggers believe that news-driven blogs like TechCrunch and Gawker are the equivalent of fast food restaurants -- great for occasional consumption, but not enough to guarantee human sustenance over the longer haul."

I'm interested in this because how people blog, and what consumers want and expect from blogs, is important as more and more news is aggregated and created on the Web.

Is blogging, for those who do it for fun and those who do it for their profession, changing? Does it need to change to produce better journalism? Would love to know what you think...
