We have changed the way we support multiple languages, and now all listings on the site are translatable whenever you want, into over 50 languages. I know, the translations aren't perfect, but not bad.
BTW: You may wonder why we chose the 7 languages flags we did.
English, French, Spanish and Chinese are the top 4 languages in North America.
Arabic and Hebrew where added because I find right-to-left languages intriguing.
And the 7th language, Swahili, was added because my wife, and co-editor, is Kenyan.
