Jeff Korhan has a point.
One of the top excuses that businesses are using to convince themselves that they don't need to do content marketing is that it's already been done. It's not uncommon for businesses to think that the content that's relevant to their market has already been written about and put out by others. With the ever-developing Internet, though, this is hardly an excuse at all.
Jeff brings up the great poit that "most problems are chronic and original perspectives are the only way to slowly break them down to develop sustainable solutions." Just beacuse there's content out there, doesn't mean that there isn't anything you can add to it.
