I noticed that for newly created tags, the code language (which is used when highlighting the code written in a post) is by default set to "none."
I get there must be a reason for using that as default language, and I am wondering in which cases it is correct to set it to default, or any other value.
What should I do, before changing the code language set by default? Should I check there are questions/answers showing code snippets, and verify that is the common case for questions using that tag?
