There is one thing that bugs me about Facebook.
It seems easier to add people you never heard of, than people you actually know.
FB is based on the premise that you know email addresses of all current and old friends, it seems. If you find an old college friend or coworker from way back, if you don`t have the person`s email, FB tells you you are engaging in behavior that can be construed as harassing, and might result in cancellation of your account.
To say the least, I find that amusing. Isn’t the whole point finding old friends and reestablishing connections?
Maybe there is a silly ISO standard that calls for this type of policy…
