The language selection is useless, even with a limitation to English. The problem is probably that normal methods of attributing language are more or less based on longer text - and not text stripped down to 140 chars or less.
If you want to make detection f.e. in search, rather get all results and apply common sense methods, like grep special words which most likely are only used in your language of choice. For real 'select your choice here' it is not going to work. At the current rate, this is rather hurting than helping. I instruct users in my book to rather use search which will limit itself, i.e. use German words if possible in search.
