I sold $PINS at the open. My thesis was mostly around monetization potential, social commerce/shopping adoption and AR/VR. Those are still there, but:
$PINS partnered with $SHOP for shoppable pins, and so I'll still have an exposure to success of that
$SNAP I believe is better positioned for AR/VR execution and they are already working with brands on those experiences. Most of their userbase is interested in commerce w/AR filters and used to using AR overall
$SNAP's pace of innovation is greater than of $PINS, in my view
