You could be right. I wouldn't conflate "novel" with "new or cutting-edge" (one can still do novel things with old tech) but even just limiting it to novel may be unfair. I guess this is just something I associate with HN submissions from experience - many things posted here really genuinely blow me away. This didn't. The normal reaction to that might be to just say nothing, but given the browser support issue, I commented.

Given that I was additionally mis-attributing the non-cross-browser functionality to the author (see edit - it works fine in Firefox), my own subjective reaction to it is probably that little bit more unfair again now.
