Without some context on where the thread was posted, it can be easy to misread what the topic actually concerns, unless you make habit of double-checking the name of the subforum you are in before commenting, which can be tedious and unintuitive if you view a lot of threads.
In short, a thread about a bug in one language can be mistaken for a thread about a bug in a language with similar syntax, and the difference may lie entirely in where the thread was posted. This can easily result in confusion, and unhelpful responses to someone's thread from people that don't know what language they're using.
