@oristarA,
That's a kind of slang; in this case, my own slang. People sometimes use the word 'wise' attached to some other word, or after another word, such as money wise or fashion wise, as in "Fashion wise, she wears clothes that are completely out of style". It is used instead of saying "In regard to fashion, she...."
I happen to like word play and sometimes make up my own words. This can throw readers off - so don't always trust me to be speaking correct english usage.
In the example about Farmerman's spelling, I was trying to say he has quite a good reason for not always typing and spelling perfectly. So, when I said
spelling word wise, I meant "in regard to his spelling..."
