Adobe's Lightroom Team has just launched a new blog called "Lightroom Journal" where they will be posting inside information, tips, and techniques for Lightroom. Their inaugural post says:
This is the place where you will find all the inside information, tips, techniques, and hidden secrets you need to help you get the most out of Lightroom, made available to you straight from the horse's mouth: the Lightroom team. Once in a while, you may also find links to web photo galleries posted here, as most of the team members are accomplished photographers in their own right. Knowing this crew, there will also be a healthy dose of random, but related posts about all things digital and photographic. But mostly it will just be a place for you to follow the inner thinking of the team, as we work our way toward making Lightroom better and better with each daily build.
