...is there something I'm missing? While I'm not sure I agree with parent's conclusion, they bring up valid topics for discussion and seem to be contributing value to the conversation. Is parent poster known for creating new accounts, and how can you tell? Why do you believe that they did not simply decide to create an account to comment here because they had something to contribute?
Also, there's a certain irony to this being your second ever comment.
Also it's not hard to imagine the sort of situation what would make one hesitate to speak frankly on the record about economic prospects for China: living there or doing business with people who live there.
Like you said, I normally don't post comments, so I agree there's irony here. However, recently I found some newly created accounts posting comments like the one above. Some of them are getting warnings from admins. Granted my comments aren't contributing either. So, sorry about that.
"Throwaway accounts are ok for sensitive information, but please don't create them routinely. On HN, users should have an identity that others can relate to."
There's room for interpretation here, but I think it's fair to say that the preferred default is the consistent use of a single permanent identifier. Do you prefer a different approach?
