And, tell us about your workflow!
I've been happily using Lightroom since the LR1 days.
But, something that can catch people off-guard is that the Lightroom/Catalog system is designed to be a comprehensive workflow manager, and you can cause needless hassles if you try to mess with your files and folders outside of the Lightroom "system".
For example, if you decide to move files and/or folders around, or to rename them or such, well, you can do that with no hassle in Lightroom and it manages things well. But, if you do them outside of Lightroom, then Lightroom will "lose" the database/catalog reference and you have to redirect it to the proper files/folders. You can do that, but it's more efficient to do it within Lightroom!
