Ask HN: Reverse asymmetry to combat dismissive comments on HN?

Dismissive comments about new things bother me partly because there's an asymmetry that seems unfair. It's so risky to create something new, and so easy to dismiss it. At their worst, the people making such comments are like schoolyard bullies picking on someone who tries to do something different. -- pg (https://news.ycombinator.com/item?id=5364566)

It seems to me that people who have put made something on their own, put themselves out there, are less dismissive in comments. That would partly explain why HN in its first year was less mean - the people participating were more likely to be makers and founders rather than trolls and armchair opinionators.

Would it be possible to create a sort of reverse asymmetry, a soft filter, where people have to show "proof of work" in order to have their comments count or rank higher?

The point isn't to create a kind of expert stamp, but more about showcasing experience and empathy with the creative and difficult aspects of making something new.

What are your thoughts, HN? Is something like this possible? Is it desirable?
