I just saw an interesting topic in a thread that I don't have permission to respond to yet. So, I thought I'd bring it up here: How often do you see other vapers other than at specific vaping events? Also, (idea from that thread, admittedly not an original thought), should vapers acknowledge one another when they see each other in public? You know, like Corvette or Harley owners give each other the subtle wave and head nod when passing other Vette or Harley owners.
