Lightroom seems to be a different breed of animal than any other software you may have used before.
We have seen people, like hsbn, who pick things up easily.
We have also seen people, like pintree3, who are totally befuddled by Lightroom (and yes, I do believe they are pretty smart, but that doesn't mean you can figure out everything). Which is probably why Adobe (and many others) make tutorial videos ... not just to show the fine points which might be difficult for most people to figure out on their own, but also videos to show the basics of using Lightroom. The fact that so many people "love Lightroom" ought to give you some idea that this is something you might want to spend time learning; and if you sepnd the time and learn Lightroom, then you can decide if Lightroom is something that you want to use or not — as hsbn said, not everyone (not even close to everyone) uses Lightroom.
