I think it depends on how long you've known the online person. I wouldn't add someone that I haven't known that long. You got to be cautious though and follow your gut instinct.

The internet is a mixed-bag. There are perfectly, normal folks who are harmless. And then there's the wackos. And sometimes the weird ones pose as normal people for all kinds of strange reasons. And some of them will lure you in and may have the skills to identify sensitive information about you like your name, address, etc. And that can be a real unsettling feeling.

I think you're okay adding GT folks. Anywhere else though... proceed with caution.
