Apple has pushed out iTunes 11.2.1, a bug fix update to yesterday's iTunes 11.2.0 release that, for some people, caused their /Users directory to become hidden. If you had the problem, check out Software Update or the link below and get with the downloading.
This is a problem that Apple has acknowledged with a support posting:
OS X Mavericks: Users folder isn't visible after updating to iTunes 11.2
The folders listed below might appear to be missing after installing iTunes 11.2 on OS X Mavericks. This can happen if you have Find My Mac enabled in iCloud System Preferences.
Update to iTunes 11.2.1 or later by running software update on your Mac.
