What a dumb response. People will do what's comfortable and effective for them, and leaning back on a couch with the rather small and light wireless K800 keyboard on the lap is comfortable and effective for some of us.
My 518 mouse works beautifully on the lip of my couch so I have no need for a firmer surface or a mat. For example, I'm often top 3 in TF2 when playing as the twitchy Scout or using the Demoman's Loch 'n Load skill weapon.
It may not be the method for you, but no need to criticize those of us who are having fun with the arrangement.
