where is the user library folder

Where did Apple put the users' "Library" folders in Lion?! If they no longer exist, where should I go to find the user's "Application Support" folder (which I always used to find in the user's "Library"). Am I missing something? Am I blind? I never used to have this trouble. I need to change the default file for a program and that file resides in the "Application Support" folder within the user's "Library" folder (at least, it always used to reside there!)

I can't seem to find anything about this in the help files that come with my computer.
