A relief to read this is an ongoing thing. While I haven't kept a list of them, I get the sense in online dictionaries that usages and examples of many words I have used have been edited to reflect very recent and modern trends over the last 10 years. I don't know if there has been any project to track drift in changes to definitions, but somewhere along the way, I stopped fully trusting dictionaries as authorities on definitions and usages as they weren't always reliable as a source to reflect the culture I was raised in. While culture changes, I sensed something insincere and contrived about online dictionaries. I wish I could find an example that sources this belief.
