Native English, Portuguese and Spanish speaker, I have lived in several mainly European countries. Currently only visited 4 continents.
I believe in a universal language for communication, English. Therefore, I only truly collaborated on the English Wikipedia. But I also contribute to the Portuguese Wikipedia and Spanish Wikipedia but I prefer to stay on this side.
Some wikipedian user pages tell their life story or reveal all sorts of interesting details about themselves, whilst others define their interests and values. I do not really want to do that, because I do not want to tempt the reader to stereotype me as unfortunately there are many editors that attack others and try to do it on a personal level rather than being non biased and objective to articles.
