A good analogy to use is c# and VB in .net. I was a VB developer and when C# was born, I didn't want to learn it because I can do everything in VB. It's the same framework so the language didn't matter. Overtime almost 99% of code examples and open source projects were written in C# and I ended up moving to c# and haven't written VB code (and don't want to) in several years. My point is, you want to blog/collaborate in spanish/frensh or whatever language? Go for it. But you have just considerably shrunk your audience and network and greatly diminished your chances of giving or getting help. PS: Wikipedia is different than code and is not a good analogy. If I want to learn about Cancer/Golden Retriever/Panama Canal/etc.. then yes, I want to read it in my native language.
