No, this isn't a good site for "What language is this?" questions.
These questions don't help "make the internet" better. They don't help future visitors to the site and they don't really help the asker. For most languages you have lots of clues that tell you what the language is, and if it's really that hard to work out then it must be a really obscure language that very few people use.
The fact that other sites have the identification tag doesn't mean that we should have one. On a personal level I don't that the other sites should have one either.
