It crossed my mind that my arrival on many of your friends lists was not unlike that. I very rarely announce my arrival, and I do lots of searches for people I think I might like to make friends with, even people with no friends/interests in common with me. Also in the early days there was very little information on my userinfo page, not for any suerreptitious reason, but just that I hadn't thought of what to say.
So does that make me a stalker?
What did you think when this crazy woman from Oxford started asking questions about you?
Did I offend anyone?
If not, what makes me more acceptable than the others that get classified as stalkers?
