Also we've been working (stopping and starting) on this problem since 2009. Here's the Hacker News post for the original implementation, In-a-Moon: https://news.ycombinator.com/item?id=586798 https://news.ycombinator.com/item?id=586798 There was a lot of learning that went on during that time. The biggest difference in implementation though was that In-a-Moon required sites to install JavaScript snippets, and we tracked at the site level. For Atri, we're bypassing sites and going straight to individuals by looking for Twitter handles.
