It could be dangerous, for some definitions of dangerous. The key question is whether it gets you something good to offset the theoretical danger.

I think SN is whatever it turns out to be. Which sounds like I'm being flippant, but I'm not. If the SN peeps want it to be exactly what HN is, except with zapping, that's one vision, and this idea wouldn't fit. If they have a more expansive idea of what online community could be, that would suggest different things.

I'm not sure if they have a commitment to any particular paradigm. That would be another key question.
