Hype-Amplifier

I recently refactored my Hacker News Amplifier 1.6 (Chrome extension) and added some new features:

  1. support for Reddit, so a name change was in order: the new version is Hype-Amplifier 1.7
  2. a little animation for shifting to the right news with less points and comments
  3. a separation of concerns, with all amplification code based on callbacks specific to each news site
  4. upload all code to https://github.com/aercolino/Hype-Amplifier, ready to be forked

Google Chrome Extensions/Apps for Hacker News

I collected all data between 2012-02-02 and 2012-02-03.

I tested all the 50 extensions/apps with news.ycombinator.com; I did not test all the other HN domains (news.ycombinator.org, news.ycombinator.net, hackerne.ws).

The order in which the extensions/apps appear below is not significant, except for the ones I tagged very useful, which come first. (broken < obsolete < 0 < funny < interesting < useful < very useful)
