This is perhaps one of the most thoughtful advice I'd seen since joining steemit. It is very common to see people lift up phrases and expressions from internet sources without adding some stamp of ownership like you rightly described. This is very unfortunate and dampens, if not destroys, the credibility of the writer.@surpassinggoogle
What I suggest is that there should be a platform where young steemians can be taught the art of writing and I know that it is expected that one know these basic things from high school and stuff like that. But let us understand that sometimes what we do in class cannot account for the dynamism of the 'class beyond' h the real world.
