That's not the case here because I consider HN to be the equivalent of a single Subreddit, so the information is less diverse. I don't talk about every facet of my life here.

On the other hand, I'm the kind of person who uses a different username on every forum. It's a habit I picked up in the early days of the internet.

This is especially useful in this era where even news organization websites will quote your online username to add to their stories.
