Anyway, just survey the Coments,  and Diaries  on multilingualism [starting with this excellent summary by DoDo from 3 months ago].

You don't see it, but a lot of the content here is translated (and, I would guess, about half is digested) from non-English sources. We have had bilingual comments, especially since I introduced the two-column format, and diaries in other languages (these with little success except for one by Afew that sparked one of the epic ET pie fights). Disclaimer: I am one of the big pushers for a multilingual ET.

Also have a look at the Eurobarometer: Europeans and their Languages to get an idea of how being an English-only site limits our reach and our potential to be the pan-European blog.

Spaniards are not far ahead of Mexicans in our ability to speak or write English, or any other languages, and diaries like this are an attempt at drawing in a crowd of Spaniards with good passive English skills.
