Maybe I speak for myself, but just like accents, I like reading the English spelling of words--and dare I say prefer it?

I think it is absolutely fine. Now, if your bigger worry is getting the SERP pages on Google, then I can tell you it is very rare that I do a search and come across an English or Australian article in my results with the English spellings.

I know that wasn't your original question, but it is a fascinating one that I just thought of while replying to you.
