These meta posts -- users sliced and diced by karma, what makes a good rating system, the role of humor (or lack of it) in a successful social site -- always appeal to my inner data nerd. It's got a bit of everything: programming, stats, html5, and, well, me. As a startup junkie, I'm all for anything that brings attention for my various efforts, like http://hn-books.com http://hn-books.com or http://caption-of-the-day.com http://caption-of-the-day.com I'd like to see a live twitter feed of the top HNers, but not just their comments here, also their public posts on FB, G+, and Twitter. To bring the volume down to size, I'd filter out the bottom 90% by karma, then maybe filter again by average. If you really wanted to nerd out, you could even allow the user to have some sliders to set their own thresholds. Seems like it would be an easy project to put together (hint, hint) I'm concerned about privacy in a big way. I know some would find my idea pretty uncomfortable, but I've long since decided that what I put on the net is my public life. I worry a lot more about my insurance company asking me to install tracking GPS devices or my local police force being able to check my ISP logs without judicial review. I'm okay with the things I made public being correlated. It's access to the stuff I feel is private without notice that concerns me a lot.
