Sorry for the “profanity” in the title, but that’s just me getting exited! Drupal is a cool and flexible platform to make powerful websites and webapplications (I may be a bit biased here). But it can be tricky to do a lot of instant, dymamic stuff to (logged in) users. Node.js on the other hand is really good at handling those concurrent actions. And now there is a module that integrates node.js with Drupal.
