I hate smileys :D I know, that sounds strange from a 16-year old ^^ but I feel like smileys are lowering the professionalism of the network :(
I would ♥ to edit all posts with smileys, but fortunately I can keep myself under control O:)
But I still wonder: do we have a policy on the use of smileys?
Related: Stack Overflow should have smileys and friend groups and especially this answer.
Useful smileys are an exception of course.
