Well, yeah, but more like 97,89%, from what I gather. From time to time I fancy this idea of toying with some NLP package to calculate percentage of the HN comments that go like "Yes, but no", "Cool, but meh" or "Sure, but no way".
The ~97% of comments that are "nice idea but..." is probably not far off the percentage of nice ideas discussed on her whose implementations don't quite work out :)
Oh wait, what did I just do?
