@Maddus Mattus: It was great meeting and hanging out with you, Matthijs. Please keep up the great work in your C9 WP app I won't forget to loop in Bart to help answer any and all Rx questions you have (he's on holiday right now, so it will be a few weeks, although he seems to write code and answer emails even when he's supposed be vacationing...).
I miss Amsterdam. I know I will be back.
One more thing, please do look up the Appsterdam folks and if you're available to present an Introduction to Rx session at one of their Amsterdam meet-ups, I can help set that up.
