I asked several of the groups if they would give me their opinion of skepticism and science topics on Wikipedia this moment in their language.
Nix Dorf sprang to the challenge and supplied us with a lot of information about what the Portuguese and Spanish pages look like. I'm really shocked about some of these pages, homeopathy in particular. The last 10:23 campaign was global, the videos created can easily be cited on the homeopathy page, we just need volunteers to help out.
The following is guest editorial by Nix, he asked me to correct his grammar, but I'm not touching a word.
Portuguese isn't wide spread as English and Spanish. Portuguese is 6th most spoken language. But Portuguese Wikipedia has more than 742,000  articles which is larger than WP in Chinese, Hindi-Urundu and Arabic which have a larger speakers base.
No language even compare to the amount of articles available in English. Even so English is not the most spoken language in the world as the number of native speakers; there are lots of people that have English as its second language and most English speaking countries are very industrialized too. On top of that USA is a well-known leader on all that happens online.
But when we get to evolution, homeopathy, religion, skeptics then it gets worse. Let’s go to a few examples.
The Randi article is very bad, compared to the English version. When I was changing it, I couldn’t resist and had to change Randi's picture itself. The former one wasn’t very nice and it had no bio info (birthdate, birth place, etc).
Evolution pages have some discussions and back and forth reversals on ID and some had been blocked for edition sometimes. But the pages aren’t much biased. But they certainly should be improved.
My personal pet peeves are the Articles on Spiritualism. With more than 3 million followers it is a big religion in Brazil. One of the most important icons was very famous woo woo called Chico Xavier, that is called by Wikipedia as a medium (not a supposed medium) and is very mild on criticism, while almost states that he was the true thing. When you compare these spiritualist articles with Shermer’s, and Randi’s you realize how big are the challenges that we may face.
Spanish Wikipedia as whole.
