You've mentioned this approach before and I think it's very interesting. I don't usually have the diligence to circle back around and see how the discussions are evolving, but I'm glad that's something you're doing.
I've definitely prematurely zapped someone and regretted it later when they said something dumb.
I totally agree, "Zap wisely". I'm trying to get people to think about what that means, though, because I don't think it's what they're doing and I think SN will be better if they start.
