When is it time (to change the status quo)?

Is it ever okay to end on a preposition? Or to use contractions?

To replace bibliographies with hyperlinks? Or active voice with passive?

Finally, is 'because' ever an appropriate way to start a sentence?

Most twenty-first century grammarians will tell you no.

They’ll tell you that because that’s the way they were taught. And because "that’s the way we’ve always done it.”

But, of course, that’s not necessarily true at all.

The real reason 21st-century grammarians will tell you not to do these things is because we live in the 21st-century. A sliver of time and space and culture.

Not permanent. Not anymore than the hieroglyphs or shakespearean lyricism that came before it.

But right here, right now. How ‘people like us do things like this.’

It turns out that language and culture change slowly (but they do change). That the rules and systems we use to communicate constantly evolve. That it’s inevitable that what we do today will be overcome by what we do tomorrow.

Which begs the question, when is it okay to change the status quo? When is it a good time to to adopt new rules and new practices? Or to revaluate our dispositions?

When is it the right time to change yesterday's rules?

After all, if all we ever do is what we did yesterday, how will will ever get to tomorrow?
