    The points are labelled with the email address which won't always be 
the account posted from. I'm listed in both Sydney (correct) and 
Melbourne with my gmail account (actually a subaddress, 
nyamatongwe+thunder at gmail.com, only used for news posting) but I post to 
comp.lang.python through Thunderbird on my local machine through my 
ISP's news server. I expect the marked locations are for the ISP's news 
hubs. Gmail only comes into the picture when I'm sent spam in response 
to a post.

    Multiple locations for gmail doesn't imply discovery of real origins 
of traffic through gmail.
