Should questions about identifying languages be on-topic here?
Pro's
- Such Q's are often interesting by themselves;
- They may highlight some unusual usage of common languages or provide an interesting info about extinct or rare ones;
- They may let the users to demonstrate their erudition (may be an important concern for someone);
- At the moment, Linguistics.SE needs more users and more questions, so even if such questions are not {yet} on-topic, they may be included;
Con's
- There may be disputes on which language it is, provided that several relative languages or dialects may apply;
- They are not about linguistics! :)
