I use it..... I do everything before exporting, including building this website
perceptive-shop.co.uk )this site was built using lightroom only, no other software) The only thing I used to do in photoshop was a few selective adjustments, ie balancing out the sky. Lightroom 2 took care of that. All I am waiting for is someone to do a filters plugin for lightroom. Lightroom is now always my first port of call, and very often my last.
