Question: Why Can’t I See My Library Folder In OS X Lion?

I noticed that the Library folder has disappeared inside my user folder after installing OS X Lion. How do I get it back?   

Answer:

Open the Terminal app and type (without quotes) “chflags nohidden ~/Library/”. The Library folder will reappear in your user folder.

Or, in the Finder, go to the Go menu and hold down the option key. A Library option will appear.
