«[…] as a designer, it bothers me, not only because badly designed things bother designers, but because badly designed things in a highly successful product spur a lust for imitation. I don’t want our clients to think “like” works. I don’t want them desiring similarly broken functionality on sites we design for them. I don’t want them thinking users don’t need tools that work, simply because millions of users don’t complain about broken tools on Facebook. Tools like like and its sad little pop-up.
Me no like.»
