I actually met a friend of mine in high school in a similar situation. I was in the library during lunch and when walking by the computers, I saw a guy browsing Polykarbon, an art site and forum that I checked out too at the time. I bugged him, as a stranger, later about it in the halls and we became fast friends.

These days, though, I could not care less if I saw someone browsing a site I frequented. I sadly already know roughly where the people I like here on EoFF live and know that none of them live nearby me.
