The map seems to show users that are divided by continents or big nations, but there is no reference where the information originates from. Also, the name Europe is not used correctly in this picture when the countries shown in the picture does not form the European continent nor countries of European Union. In fact, the picture fails to recognise that whole Scandinavia is in fact part of Europe and Finland is also part of European continent as well as a member of European Union and Euro. It remains unclear is the Europe's user numbers really showing all European countries, Finland included, or just a sample of some European countries.
