alright, i dunno if this is gonna get shut down or something
for encouraging stalkers or whatever, but here we go!
try and guess/find out the country that the person above you is from, by means of their set time zone, Google/search engines, other [country here] only sites that they're registered on, etc. and say something to them in (what you think is) their native language.
EDIT: it just occurred to me that this will probably raise everyone's profile views a bit. just sayin.
EDIT2: also, it would be better if everyone would say what time of day it is,
making it easier to work out where you are by time zone. I.E. morning, noon, afternoon, midday, evening, night
for me, as of writing this, it is morning
