Depends on what other info you release/have released.
A lot of people don't know they release small bits of info all the time about who they are. It's not just one piece of info, its a lot (even small details you think are insignificant) added up.
I think we need to be more cautious, but people need to know the types of info to be cautious about too.
Good Luck to you. =)
