Jon Fine had a long chat with WSJ editor Robert Thomson, and got some interesting statements out of him:

Also coming: extensive customizing tools for readers to find, through search, much more Dow Jones content. (In Thomson's groan-worthy formulation, "In the contemporary age of content, the customizer is always right.")...
He also says "we're not there" in terms of figuring out what should or shouldn't be shortened. He cites Spanish dailies El País and El Mundo as favorites for their "hygienic" look--a description that cracked him up as soon as he voiced it--saying both "understood the relative weight of word and image."

I'm highly suspicious about this whole customization thing. It's been tried before, many times; it's never really worked, and it largely defeats what a great newspaper should be all about.
