This is the #3 result for a search I just did. Who cares if it's not really an important search...because the point is that GOOGLE DOES NOT KNOW WHAT "QUALITY CONTENT" is.
They very obviously have NO CLUE how to read text and decide if anything is quality or not. Even if/when they do, how could you measure that anyway?
Think about it.
All these marketers say they "Only write quality content" on their sites. So what. Compared to one of the geniuses (literally) who work at Google do you think your "great" article is "quality" in any way?
The guys at google are pretty bright...I highly doubt they would find 99.99999999% of IM sites even halfway interesting or written with quality under their standards, considering they read at what...a billionth grade level.
So anyway, disagree...who cares, but stop with the "quality content" ...it's FALSE.
