I agree, if you can read english, you got far more input. And the older light is unknown, or the crazy trash they write. So for example, that woman maybe getting mans in the new world. Also a lot of texts sounds in other languages not so crazy. Maybe they wrote it in english, a shitstorm came up and the translation was "optimized".
The languagegroups often far away from the typical congs. More fun, but often also full we special people. If a guy in a languagegroup do a little bit more, he gets very fast MS or elder. So there a lot of people looking for the expressway to the top.
You don´t have jwfacts in other languages, but nearly every bigger language got some sites with the main informations. A lot of stuff gets translated. So "Shadow of Sin" - you can look it also in german. It's harder to get a JW to look at theses sites.
