I'd love to be able to track certain users on the site. I'm not really sure what the UX would be, but potentially it could be like the homepage. It could list the users that I've tracked, show how many new comments they've made, show their karma, etc.

I'm interested in working on this, but would want to discuss the UX first.

I use https://www.hnwatcher.com/ to receive mentions of this extension and it works well for that use case. You'd probably want to use https://github.com/HackerNews/API to get the required info.

As for the UX, I'm open to anything but I'd like it to have a minimal impact on the front page. If I were to do it, I'd probably add a new item to the header called 'followed' or similar. The page itself shouldn't stray too far from the existing tabular layout.

You'd need some way to 'follow' users. I'd probably just put a button on in the users page (/user?id=) for now.
