I still keep in touch with a bunch of people from an assembly game hacking forum from when I was like 10. They're responsible for my entire career and how I got into programming! It was great. I'm still a part of a bunch of hobby specific forums and they are all going strong.

Once you start noticing HN usernames you won't stop. It's big, but it's small. Certain users gravitate to certain topics and you'll see them pop up. I think the problem is you have no style associations to usernames, like colors and icons and fonts and whatnot like you had on old forums making it super easy to visually identify people.
