I think it’s good and healthy to have folks in our community — in this case @jakobnissen — be clear and up front about what they find Julia’s challenges to be.
This has spurred lots of discussion already in the community; on HN itself (you’ll find many familiar names) and on Slack. If you’re interested in discussing this further, I think you can join in on the discussions there or you can focus your question a bit more. Without such a focus, I don’t foresee this topic being productive.
For more details about how we like to approach such topics productively here, see the POLICY: feedback discussion splitting.
