Should this site cover only spoken language or also written language, including alphabets and other writing systems? Or should it allow the latter only to a certain degree that overlaps spoken language in some way?
In my humble opinion we should try to be as liberal as possible when it comes to which linguistics-related fields are on-topic, so I would say on-topic. Ha, if doesn't fit here, then where?
I agree that linguistics.SE is the place for discussion of writing systems, if only because no other exchanges are likely to cover this topic. Even if any of the other language SEs did cover writing systems appropriate to their subject, it's unlikely that they'd be willing to discuss comparison of writing systems. So, I vote yes.
I know you have already accepted but I vote yes as well. The written language has the same rights as the spoken one to appear here.
The point is that it must be from a Linguistics point of view, that's about the only "restriction" we could have. :)
Too bad I'm late. A big YES from me.
This is now a 7-year-old question, but what I think is that:
Those questions should be off-topic unless primarily concerned with linguistics.
