Is the phrase "Back in the day..." widely accepted now?

Please forgive my cynicism. I spend a lot of time in Great Debates and I don’t agree with the majority of the folks in there, so I’m used to innuendo in responses to me. I’m sorry if I seemed defensive or snarky.

To answer your question, anytime someone butchers or dumbs down the English language, it gets under my skin. Bad grammar also sets my teeth on edge.

It’s been almost 3 years since I started this thread, and now the language maven himself is using the phrase…and in the first sentence of his column!

This is one of silliest things I’ve ever read.

I think we need a Hostile Dialect all up in here.

How is “back in the day” any different than “sets my teeth on edge”? Both are phrases that, given just the words as they are constructed, don’t necessarily mean anything. However, they are both common phrases that are used by people to express a certain meaning, one which most listeners (or readers) understand.

Yes indeed-but wouldn’t a link to this thread have sufficed?
