From Darkroom to Lightroom: Downloadable PDF:

Ken Milburn, author of Digital Photography: Expert Techniques from O'Reilly, has released a 22 page PDF to help new users of Adobe's Lightroom get to grips with the product.

Also on the O'Reilly site, there's an MP3 of an interview with Julieanne Kost, author of Window Seat: The Art of Digital Photography and Creative Thinking where they discuss 'how Lightroom could change photography as we know it'.

While I don't know if it will change photography as such, I think it's a good step in the right direction - make the computer based part of the photography quicker and easier, giving us more time out in the field, camera in hand. That's gotta be the best way to improve photography, right?
