Don't Regret
Just a little thought. A friend said I was "stalking" on Facebook earlier. I searched for the definition of Facebook and it reads a global social networking, to connect with your friends and with your friends friends.
In fact, one friend of mine actually said she was stalked a few times by strangers/someone she may know. As such, she is rather prudent not to share too much details online.
Personally, I feel it is a good idea to connect with friends across the world on Facebook. If one doesn't like sharing his social comments with his friends, he/she can set it to private. Let me know if there is an alternative or better way. I am all ears:)
