Answer

Hi, this means that most things that went viral (famous on the internet) happened spontaneously and unexpectedly, but if you try to take steps to force something to spread widely it is likely that you will fail

Answer

It is impossible to predict what information goes viral so there has been little success in trying to create artificially the information that goes viral.

I hope I made it easier to understand.
