I think it behooves us to clarify what is, and is not, a timewaster. Allegedly obscure, inane, amusing and otherwise pointless videos and diversions are not — to my mind — timewasters qua timewasters. Games and other activities which require active participation and which can turn horribly addictive quickly are what I consider timewasters. The first one, I believe, was this. Meanwhile, how anyone could call this classic cultural artifact a timewaster is beyond me.
