I assumed it would be worse technically. Perhaps if it was OK to relentlessly poll, it could be a good service. Things like votes and comment edits would be hard to capture quickly unless every single item was relentlessly polled. On the other hand I am not trying to rule out viable alternatives by suggesting it comes straight from HN, I even considered making what you are saying at one time. I just don't think it would be as good as an HN one.
