One "philosophical difference" that you need to know about is that comments like these aren't allowed here:

> I know I'll get napalmed for saying this

> And if you downvote this, tell me why, otherwise I'll just assume you are with those that want to exploit me and others.

Please reread the HN guidelines, particularly the last two: https://news.ycombinator.com/newsguidelines.html. If you're going to comment here, please follow them.

The "why is this on HN" genre is also pretty lame.
