It's definitely true that some languages are more "useful" to have than others. Spanish, Russian, Chinese and German (to name a few and not nearly all) have very active communities on specific topics. But if you cover a language that isn't well represented online (or if proficiency in a larger language is high), you're not likely to get a community and contributing on the larger wiki might feel like less of a waste of time.

However, if you've got a unique niche you fill in your language (other than it being in your language), you can make a valuable resource.

There is an English gardening wiki you can try out.
