I've been thinking of the same. I spend a lot of my time in forums and would like to be able to discriminate users based on certain parameters.
I envision it as some sort of extension that analyzes the users on the current discussion thread, visits their profiles, analyzes it (post history, stats, etc) and decorates the users handle on my current page.
Performance shouldn't be too bad using caching and prioritization.
What value adds were you envisioning specifically?
Sorry, I didn't see this the other day, I'm not really a power-user.
I guess if I could have any features I want, it'd be this:
* Topics, perhaps categorized by keywords.
Maybe, if someone uses the word "TensorFlow" I'd like to know if they have other posts that have scored well with that word in them.
* Similarly, I'd like to know what topics that user are more likely to post in. If a user only ever posts in threads that contain the word "SomeSmallStartupTheyAreClearlyShillingFor" then, I'd like to know that. I find that in practice. Algorithmically, I think its not too hard to separate these two categories and distinguish high-quality users, because the way posts can be scored here on HN.
Really though, I have been thinking about building something like this, maybe a service reading thousands of RSS feeds and keeping track of comment sections in blogs and forum threads, and just compiling these webs of influence for certain links. Like a search engine, except it'd be specialized for discovering high-quality conversations.
