Earlier I changed the default language on
mw.lojban.org to English because
1. Google didn't always correctly displayed English versions of the wiki. Falling back to English is nicer for it (who are we to challenge its algorithms)
2. Most pages are in English so using Translate Extensions to translate pages via it would become easier.
Finally if you think that it's not good to have the default language other than Lojban (and I myself think it's not good) we have another wiki that is much much better for enriching the corpus of texts.
As for
mw.lojban.org it's mostly not even worth translating articles on it, most of them are either of historical interest or for speakers of English.
Finally I can see that some search engines are able to select mediawiki's pages in other languages. But Google doesn't seem to catch on. If anyone has any ideas feel free to share them.
