I go to User/Library/Application Support on a daily basis to fix things and manage my games (Steam, Minecraft). It's an absolute necessity for me, so not only do I need access to it, but I also need easy access to it. Opening the Finder, clicking Alt + Go and choosing Library from the list is NOT an easy and quick way of doing it. The Library is where all applications store their settings. It's where all the corrupted files are that you need to delete when something goes bad. It's where games put your saved games, and where Steam puts screenshots. It's where Crossover puts everything. When you delete an app, all the crap it created in Application Support is still there, forever, unless you manually delete it.
Apple is freaking retarded for hiding it. And if they let me unhide it, fine. Just don't keep hiding it at each ******** update! I'm not a virus that requires patching at each update, I'm a user, and I need access to most things on my computer, except the actual OS X files (though it happens that something needs to be done in there as well).
