there are some of us who are involved in the internet on many levels. we grow overly cautious about revealing information of any kind to others that we don't personally know. if someone asks where i'm from, i will probably tell them--but i will remain "in hiding" in general, just to decrease the chance that someone might see it that i would prefer not.
sorry. i teach my students at the hospital to "cultivate your paranoia. it will be your best friend." if something bothers you, pay attention to that instinct. i offer the same to you. if something makes you uncomfortable, pay attention to that. revealing too much makes me uncomfortable. privacy issues (just like at the hospital, again)
