Companies like Twitter, Facebook have rolled out (Like/Hearts/emotions) button to posts. I think "heart" button is not appropriate categorization for real time contents. Sometimes we just want to express on things if they are relevant. The emotion part "Like, heart, dislike, chill, etc" is just an aftermath to the real intent. Problem: "heart" can not express emotion that community wants to just share, it may not necessarily be likable. Example, Tweet about violence in Middle east. I want to just not give it a "heart" but some other emotion like "disgrace, shame" etc. Idea: To solve this problem, I would say the real symbol should be "Star", instead of "heart, like" etc. "Star" means you want to buzz in with this article but not classify your emotion. What do you think?
