Lets have a discussion about は vs が

[-悪魔-]

Is there a definate "rule" of when you are suppose to use the two? I kind of instinctively know when to use が instead of は but sometimes I'm not sure... and I'm still not quite sure about what exactly the difference is between the two.

So lets have a full blow out discussion about this.

は is an information structure marker, and が is a case particle. Check these out:
