Good piece in ClickZ. I'm with Jeff Einstein; Eric Picard from Microsoft is obsessing over technical details, sometimes at the expense of missing the main point. Einstein says:

We've been obsessed with our own ability to measure performance (regardless of the metric) since day one online. Our obsession with efficiency and scale all but eliminates the quality of the message from the consideration set, largely because quality is much more difficult to measure and formulize. We can tinker all we want with metrics and formats, but as long as we remain fixated on efficiency and scale as the keys to the kingdom, performance will continue to decline.
