Just make a new account? Not like it costs money.

He might already have a main account but intentionally doesn't want to use it. I've noticed on X that OpenAI employees tend to post a lot more regarding their employer on their main X accounts than Anthropic employees do.

I don't use HN often, so I made an account for this purpose that would make it clear who I was in relation to the article.

You also register -openai -deepmind -meta and -xsi

Just a way to separate one's personal comments from their professional ones, like a work email address.

They throw it away?

Then there will be no more time spent trying to manage Orange Site public opinions regarding Anthropic.
