I agree, kt17 - it's nice to get a puzzle that can be completed without having to look outside of the puzzle itself, but still leaves a bit of work at the very end. And if I'd had more faith in my first guess at the 'phenomenon', I could have avoided google altogether (because that word is in the ODQ index, and does link to the quote).
However, I'm still not convinced that the 4 examples we're given are what groups them together in ODQ - they're ones that never were, rather than erroneous ones (well, I think they are - but that's not meant to distract from a fine puzzle).
