Scandinavia - big place, NESers spread out in Sweden, Norway, and Finland.
USA - even bigger, 50 states and many colonies/protectorates.
Canada - even bigger still! BIG way from South Ontario to Whitehorse.
Israel, Japan, Russia, Malaysia, Poland, etc. - all very spread out, few NESers over big amounts of space.
Even in USA - Texas, Chicago, California, Arizona, Michigan, Colorado, Virginia, and many more states have NESers.
Also, many NESers are
a) VERY BUSY - a good reason for delays in between updates, many people have lives, and cant drop everything to see other NESers.
b) YOUNG - many NESers are young, and with all the internet safety things, I can't see many 14-year olds being able to go after telling their parents "I'm going to fly to _____ to meet people I talk to on the internet. I've seen pictures of them, so I know what they look like, so it will be safe!"
I know I would not buy that if a teenage kid of mine said that to me...
