The question of spelling reform is an important one. Should there be one form – that is, one spelling, one grammar, one common meaning — of English words and terms? There are currently two to six or even more ways to spell certain words.
For example, the spellings organization and organisation are different depending on the region of the world. In the US and Canada, organization is preferred; in the UK and Australia, organisation is preferred. Exception: in the UK, Oxford Dictionary and British academics prefer organization (and I bet you knew that an exception was coming). So there can even be two spellings of a word within one country.
Then there are multiple syllables that can vary within a single word like: sulfurization, sulphurisation, sulphurization. Next add a prefix, with or without a hyphen: desulfurization, de-sulfurization, desulphurisation, de-sulphurisation, desulphurization and de-sulphurization. And the list goes on, in fact there are tens of thousands of these two types of spelling variations in English.
Does it matter which form we use? In all cases we understand the word. But in writing well the credibility of the author is questioned. Does this person think clearly and consistently? If their spelling lacks consistency, is their thinking just as inconsistent and unclear?
Consistency, clarity. Let’s leave no doubt and use one spelling, at least in the same document.
NOTE: By the way, and just for fun, see what a differences punctuation makes. Spelling rules: ~ Spelling rules. ~ Spelling rules! With a colon it is a noun phrase where you can expect a list to follow; second, a complete sentence, where spelling is the noun/subject and rules is the verb, “to dominate or govern”; third, spelling is the noun/subject and rules is an informal verb meaning “is the best”. So what’s the message here.
