In spoken language, I would most likely not really be able to understand that, but in written language I can read it with not much trouble at all. Certainly, nearly all the words are spelt differently than I would spell their English counterparts, but it's obvious which words they're cognate to. I certainly wouldn't say it's "difficult" for me to read either.
So why do we have a Scots Wikipedia? Or maybe we should get rid of the English Wikipedia and convert everything into Scots.
