"Mesaging service Snapchat reportedly turned down a $3 billion offer from Facebook?!"

Everyone has his opinion about this,but in my personal eyes,life is to take risks,and  it's not all about instant money.Nobody knows about the future in advance.Althought everything may change in just one second,we have no ideas how might it change,better 0r worse,and if u think there is a fair business environment and a good perspective,u should be bold to have a try,meanwhile,to follow the time,to add other features that user like(but do not make it complicated).Developing is about a long journey in which u should take care of everytings,even trivia.In this way, you can succeed.
