It’s not uncommon; and if you consider that written English is actually a subservient to SPOKEN english, because we subvocalize as we read, “would of” is correct when reading it, not by dictionary definition but by hearing it while subvocalizing while reading it.
For sure. I mean, if this was a job interview, a school lesson, a writing that got payment or was for public broadcast, a prescriptivist correction is warranted.
But in this environment it’s play.
But yes, I’m definitely a descriptivist by far. Things change far too quickly to try an crystalize language into fixed forms.
It’s useful in negotiating meaning; everybody in a discussion needs to agree to common terms, which can take a while sometimes; and is often the entire discussion. But I think it’s probably the most important thing. Many issues are entirely resolved once meaning is negotiated as that was often the problem all along.
