Not us. We never show all language flags. It is suboptimal to have GoogleBot indexing links with little traffic benefit or upside.

I never recommend to anyone to enable all languages on any forum large or small.

Having said that, few people follow my advice. They simply load all the flags without regard to traffic patterns in the Internet.

Keep in mind also that there is a maximum number of links that GoogleBot will index. I have no idea how Google determines what the ceiling is, but I can tell you that the longer you index, the slower the progress is.

For this reason alone, you should index the high priority languages first (expose those flags and create site maps). It is a major mistake to simply expose languages without a plan. Make a plan ! Use Google Analytics to ANALYZE your site performance. Use Google Webmaster tools to optimize your sitemaps.
