Another fun one, post on HN, wind up on Google Instant Answers, and quoted by Gemini (or whatever the model there is). There's been a few times I've googled something insanely niche, clicked through only to find my own comment as the source, turns out my mind runs in cycles where I randomly ask questions I've formerly answered, and now I can answer them for future me.
It's both a blessing and a curse, especially if I'm wrong. Sometimes the Google AI misappropriates someone else'se quotes to me, not sure why, though those are usually if I ask it about myself directly and it tries to generate a summary of my HN post history.
On one other occasion... it was a post I had posted 2 weeks prior, I was trying to do further research into the subject.
