I like them a lot tbh. I think its got a good scope of variety and if someone really likes or dislikes something then that gives them the option of voicing their opinion with a reply. As for what the new set of buttons says, I think its representational of how people can react to something. It gives people the chance to give their thoughts on something whether they feel it is off-topic, Insightful, Ludicrous, Awesome, or Funny. For the people that dont feel a reply is necessary it gives them the opportunity to still voice their thoughts, just not with a reply. Thats why I like them. :)>-
