Not long ago I watched a free software developer totally lose his cool with a user who (admittedly very frustratingly) posted a “bug report” in Spanish on an English-language project that amounted to “it doesn’t work”. He posted a very sarcastic reply in a couple of random languages (one of them through a machine translator). It was an understandable reaction, and in a way, kind of funny if you could understand all of the languages involved, but it wasn’t exactly good public relations. It was a sure sign of burnout. He had forgotten one important point: you are not obligated to help just because you wrote the thing.
