It was kind of test from our side. In future we want to publish articles also in other languages than English. These articles will be in the Multilanguage Corner category and will have some summary in English on the top, maybe with link to the google translate into English... Depends on Julia and Milos, I think.
Yes, Chocholo is right.
As our community is global, and our blog is not, we decided to ask our in-house team members, who also help us greatly with translation/localization, if they would be willing to help out. It's a sporadic effort because of that, but you'll gradually see various language corners appear in the list of categories, with only English posts set to display on the blog home page.
Right now we've got about a dozen non-English blog posts - Spanish, Portuguese, Polish, Japanese, Czech, and Turkish. It wouldn't take much to expand this, but our people are busy enough with their primary responsibilities. It will grow, though.
BTW, here's the latest "5 Questions" interview, with our longest-running team member, Vladimir Cernik:
