Introducing Steam Labs! We create a lot of experimental features behind the scenes at Steam, and for the first time we’re giving these works-in-progress a home. Pop on your lab coats, check out Steam Labs and share your feedback with us! (Steam Twitter)
so far its pretty cool to check out the stuff that is WIP from steam plus they are also taking feedback from users to perfect these features. so far i like the new “Interactive Recommender” seems much better then any of the other recommended feature stuff.
