Gosh, comments like these from the actual author are a reminder of why I love HN. :)

I'm also amazed by the fact that that John Nagle from the popular Nagle's algorithm is still active on HN!

There are lots of known people on HN. I started tagging HN usernames with a browser extension some time ago and sometimes I spot some really interesting exchanges given the context of what the posters worked on.

I'd like to more about this. Can I use this?

Search for HN username tagging extension. There's quite a few options available.

Is this collaborative? That is, can one benefit from other people's tagging?
