I got me a couple of those "world time" programs which show, in a couple of different formats, what time it is anywhere in the world. Very useful when you wonder about a good time to try to meet for a chat! I just noted, for instance, that London is 5 hrs ahead of New York, and Sydney is 14 hours ahead of New York.....So..I am typing at 11am,it is 4 pm in London and 1am in Sydney....not a very good configuration....but on a weekend (say Fri or Sat nite..), I could get on at 6 pm, London would be at 11pm (not too bad for a short chat) and Sydney would be at 8am Sat or Sun morning!...really possible, if 3 people in those locations really wanted to have a chat! No time is 'Just right', but any 2 can plan a time and invite anyone who is awake to join in...and as 'needs' develop, times will be found.
.... The real problem is that we are not at 'critical mass' yet to have enough warm bodies available who know about this, have a machine with the right kind of browser, and are of a mind to communicate in this format in the 'Brave New World'. Don't everyone give up...just recruit!!
