But the rule "Is it indicating possession? Use an apostrophe" is not sufficiently qualified in this chart.
So following that rule, I would right "hi's apostrophic flow chart didn't contain enough qualifications to make it's meaning accurate or clear."
Also, I quite like signs advertising "CD's and DVD's" because they remind me that the letters 'isc' have been omitted.

The English language is far too stressful.

There's an error on that flow chart.
It should be "90s' fashion" not "90's fashion" UNLESS you are talking about the specific year 1990, rather than the entire decade. But it's probably in reference to the decade, in which case it's denoting a plural -hence "90s"- and then a possessive of that plural, hence "90s' ".

I would think they are talking about 1990 – because Hammer pants weren't around for that much longer…
Also, the apostrophe after the s rule is not actually a hard and fast rule. It could be 90s's and still be correct.
Gordon,
There are a few more bits to the flow chart if you follow the link… but I would point out that for consistent use of the apostrophe in DVDs it should be D'V'D's. And that's not pretty, nor does it fit with any rules for acronymising words…
