It's not awful, but I feel it's still pretty meh. I say this as a person raised in Edinburgh in the sixties and seventies. How bad? Well.. in their backend meta pages they link to the DSL (Dictionary of the scots language/dictionars o' Scots Leid [0]) which says this:

Written Scots In the written mode, Scots spelling remains variable. Attempts to make it more consistent, notably the Scots Style Sheet produced by the Makars’ Club in 1947 or the Recommendations for Writers in Scots published by the Scots Language Society in 1985, have had at best only limited success, competing with other systems that have been developed to represent more closely localized varieties of spoken Scots.

When your reference text says the language isn't yet well captured in a single print, you better believe the wiki page is a hot mess.
