So... while this is cool and all, this isn't anything revolutionary or even 'new' that couldn't have been done in any other scripting language/framework (and, in fact, I daresay it could've probably been done faster in another language/framework).

While I believe Node is pretty frickin' awesome, I don't see a point in glorifying concepts that have already been done to death. Nodes entire architecture allows so many more possibilities than just a HackerNews clone, so let's see it instead of constantly reinventing the wheel.
