My first thought when I read the poll was, "What about everything between the US and South America?". I think the way these polls are written tells more about the person writing the poll than anything else. I can't imagine the usefulness of splitting the US into NYC/SF and everything else. Likewise with splitting the UK and the rest of Europe.

The UK is definitely a special case cf. the rest of Europe. For one, there is common language to consider. Secondly, it appears the UK makes up the next largest userbase after the USA. It is as if to say 'why separate Canada from the US'. Similarly, NYC and SF are the prominent start up areas. Knowing who is in and out of these has uses.

My take was that the OP would like to do every country, but obviously must limit numbers to something sensible.

Je suis @ Mexico aussi. We are North America!!!

I am in Mexico too. So either North America if you go for a geographical division, or Latin America, if you wish to characterize culturally.

Same here, from Baja.
