@Sarah I don't think you understand.

The site saying I'm looking at this page in Deutsch even though the text is Dutch is like the English version of the site saying the language is French.

@ Sarah: Sorry to get you mad! Haha... but if you read better, you'll notice that I wasn't at all trying to explain the differences between those languages whatsoever. I was only trying to show a way to slightly improve this website. I couldn't find a place to directly get in touch with the ones maintaining italki, and so I decided to dedicate my first discussion to this common fallacy.

I kinda like your resolute struggle for knowledge though!

I don't understand how anyone could confuse the two countries. Dutch architecture is unlike anything else in Europe or the world. (excepting, like, St. Maarten) 

You would be surprised to notice how many think people in Holland speak German!

While I was living in Taiwan I have to explain to both Asians and Americans that the suggestion is pretty sensitive in Holland.

I told the Americans that is like saying that Canada is part of the USA! Then they got the message: "That bad, he?!"

To give them an idea I told them that a Dutch comedian once joked that "it is good that the Germans broke down the Berlin Wall but they should rebuild it on the Dutch German border!"

There was also a very kind German bloke who loves to go to Holland but he showed a painful face when I told him that according to many my native language is German in stead of Dutch! 

Sorry but if the fact that one language is spoken in one country and the other language is spoken in another country is the big difference between two languages, then you don't understand anything about languages. This is probably the most useless explanation to tell people why two languages are different (and why something should be changed on a website)! What about English in Australia and English in the UK?? What about Luxembourg where they have 3 official languages (2 of them are also spoken in other countries)?? etc etc etc

If you google a bit, you'll find many reasons why Dutch and German is different (most of the differences are grammatical) - but surely not that Dutch is spoken in the Netherlands and German in Germany!

But still: "Dutch is part of the German branch of the Indo-European language family. It is, therefore, closely related to English, German and the Scandinavian languages." (http://esl.fis.edu/grammar/langdiff/dutch.hmt)
