One of the things that I do when figuring experience is take into account the In-Character Discussions. As you've all seen I give "Base and Role-Playing Experience".
ICD's are a great chance to do what normally cannot be done in a session:Role-play everyday life of a character. John Lennon said "Life is what happens while you're busy making other plans". I take great stock in attempts (and success) in detailing the everyday life of characters. It might be considered "mundane" by power gamers but you're anything but.
To use a football analogy: I'm the quarterback throwing the ball for the play. My receivers (you guys) catch the ball and run with it as far as you can. You all do a great job in getting the touchdown!
You're adding to our campaign and take the time to do such. How can I not reward that? I'm not trying to bribe you with experience I'm just letting you know that what you contribute counts for much in my eyes.
