It's not SAFE to reveal personal information online because you NEVER know how it will be used, or by whom. Once posted online it can NEVER be taken back and so if technology changes, or some service like driver's license, passport or even your member card at the video rental store changes their policy it's possible for someone to impersonate you many years later.
Is it a problem? If it's forced, yes. I was told by Google that I MUST use my real name in my Google+ profile, which is why I'm not active on Google+. If I wasn't married with children I wouldn't care as much but MY information can be used to impersonate me to get at them and their information... and that's not ok. Yes, Google forces people to use real names and/or gives them the impression they have no choice. I'm surprised people haven't complained more loudly sooner.
